摘要： A beam steering antenna structure (1) comprising a printed circuit board (2) and a conductive component (3), a first wall (4) and a second wall (5) of the printed circuit board (2) being juxtaposed with a first surface (3a) of the conductive component (3), the second wall (5) of the printed circuit board (2) abutting and being galvanically connected to the first surface (3a) of the conductive component (3). A second surface (3b) of the conductive component (3) extends at an angle (α) from the first surface (3a) of the conductive component (3) in a direction from the first wall (4). A connecting surface (6) extends between the first wall (4) and the second wall (5) such that a groove (7) is formed between the first wall (4) and the second wall (5), the groove (7) being at least partially juxtaposed to the first surface (3a). The groove (7) comprises a first antenna array (8) and a second antenna array (9), the first antenna array (8) transmitting or receiving a first radiation beam (B1) having a first polarization (P1), the second antenna array (9) transmitting or receiving a second radiation beam (B2) having a second polarization (P2), orthogonal to the first polarization (P1). The second surface (3b) steers at least one of the first radiation beam (B1) and the second radiation beam (B2) in a direction away from or towards the connecting surface (6). This allows changing the direction of the main lobe of the radiation pattern of at least one of the radiation beams such that the two antenna arrays transmit or receive in the same direction.

摘要： A dual-polarization antenna module (1) for generation of millimeter- wave frequency radiation, comprising an antenna (2), a first conductive structure (5) and a second conductive structure (6). The antenna (2) comprises at least one first antenna element (3) configured to excite a first electric field (F1) having a first polarization, and at least one second antenna element (4) configured to excite a second electric field (F2) having a second polarization. The first antenna element (3) and the second antenna element (4) extend in an antenna plane. A dielectric volume (7) is partially enclosed by the antenna (2), the first conductive structure (5), and the second conductive structure (6), a first surface (8) of the dielectric volume (7) being open to an exterior of the antenna module (1). The dielectric volume (7) allows the first electric field (F1) and the second electric field (F2) to propagate, within the dielectric volume (7), from the antenna (2) at least partially towards the first conductive structure (5), and radiate from the first surface (8) to the exterior. Such an antenna module is very flexible and can be easily integrated in mobile electronic devices or any other device with similar space requirements, while also facilitating dual-polarization.

摘要： A dual-polarization antenna element (1) comprising a first conductive structure (2), a second conductive structure (3), a first antenna (4), and a second antenna (5). A first main plane of the first conductive structure (2) and a second main plane of the second conductive structure (3) extend at least partially in parallel. The first conductive structure (2) comprises a first aperture (6) having a first configuration, the second conductive structure (3) comprises a second aperture (7) having a second configuration different from the first configuration, and the first aperture (6) abuts the second aperture (7). The first antenna (4) is formed by the first conductive structure (2), the second conductive structure (3), and a first antenna feed (8) comprising a first coupling element (9) configured to excite a first electrical field (F1) having a first polarization. The first antenna feed (8) extends through the first aperture (6) in a first direction (D1) perpendicular to the first main plane and the second main plane. The second antenna (5) is formed by the second conductive structure (3) and a second antenna feed (10) comprising a second coupling element (11) configured to excite a second electrical field (F2) having a second polarization. The second antenna feed (10) extends along the second aperture (7) in a second direction (D2) parallel to the first main plane and the second main plane. This allows dual-polarization, and hence sufficient gain coverage to be achieved in any direction from the electronic device into which the antenna element has been mounted, without negatively affecting, e.g., the mechanical strength of the electronic device.

摘要： A transmission line (1) for transmitting radiofrequency range current between a first conductive element (2) and a second conductive element (3), the transmission line (1) comprising a signal current line (4) and at least one return current line (5), the signal current line (4) and the return current line(s) (5) extending in parallel. Each current line (4, 5) comprises at least one first segment (6) and at least one second segment (7). Each first segment (6) is partially aligned with at least one adjacent second segment (7), aligned segments being separated by a first dielectric gap (8), and each aligned first segment (6) and second segment (7) forming a capacitive coupling across the first dielectric gap (8). This solution enables a transmission line which provides only small capacitive loading onto its surroundings, and which therefore can extend, e.g., through an antenna element without significantly affecting the performance of the antenna element.

摘要： A beam steering antenna structure (1) comprising a stacked antenna module (2) and a first conductive component (3), the stacked antenna module (2) comprising a first substrate (4) and a second substrate (5). The first substrate (4) is arranged superjacent the second substrate (5) such that a main plane of the first substrate (4) extends in parallel with a main plane of the second substrate (5). The first substrate (4) comprises a first antenna array (6) transmitting and receiving a first radiation beam (R1), the second substrate (5) comprises a second antenna array (7) transmitting and receiving a second radiation beam (R2). The first conductive component (3) extends adjacent the stacked antenna module (2) and is at least partially separated from the stacked antenna module (2) in a first direction (D1) perpendicular to the main plane of the conductive component (3). The stacked antenna module (2) is coupled to the conductive component (3) by means of at least one of a galvanic, capacitive, or inductive coupling. At least one of the first radiation beam (R1) and the second radiation beam (R2) are at least partially steered in a direction away from the other one of the first radiation beam (R1) and the second radiation beam (R2) by the first conductive component (3). This allows the radiation beams radiating from the antenna structure to be steered, at least partially, in one or several directions, such that sufficient gain coverage can be achieved in any direction from the beam steering antenna structure.

摘要： A redirecting structure (12) for electromagnetic waves having a wavelength (λ), the redirecting structure comprising a first reflection passage (1) formed between a first conductive surface (2a) of a first conductive element (2) and a first conductive surface (3a) of a second conductive element (3), as well as at least one antenna structure comprising at least one antenna element (4) and at least one radiation passage (5) extending from the antenna element (4) in a first direction (D1). The antenna element (4) is configured to emit electromagnetic waves, the electromagnetic waves propagating at least partially through the radiation passage (5). The antenna structure is connected to the first reflection passage (1) at a first interface (6), the first reflection passage (1) extending in a second direction (D2), the second direction (D2) being different from the first direction (D1). A first reflective structure (7) is associated with an interior of the first reflection passage (1), the first reflective structure (7) being arranged at a predetermined distance (X) from the first interface (6) such that electromagnetic waves propagating from the antenna structure into the first reflection passage (1) are reflected to the radiation passage (5) by the first reflective structure (7). The first reflective structure (7) extends in parallel with a longitudinal extension of the antenna element (4). The redirecting structure prevents destructive radiation fields from propagating through passages existing between the conductive elements of a device, such as between the display and the frame of a mobile phone.

摘要： An antenna assembly includes a first antenna array disposed on a first side of a substrate and at least one second antenna array disposed on the second side of the substrate. The first antenna array is made up of a first monopole antenna element and at least a second monopole antenna element. A metal strip member is coupled to the first monopole antenna element and to the second monopole antenna element. The second antenna array comprises a dipole shaped coupler. The first antenna array and the second antenna array are spaced apart by a predetermined distance and occupy a common space. The aspects of the disclosed embodiments provide an antenna arrangement that is extremely compact since the geometry of two differently polarized antenna arrays is shared between the antennas. Physically smaller antennas are beneficial given the small volumes available for antennas in devices with big displays.

摘要： A beam steering antenna structure (1) for an electronic device, the beam steering antenna structure (1) comprising a first conductive element (2) and a first antenna array (3). The first antenna array (3) is adapted for at least one of transmitting and receiving a first radio frequency radiation beam (R1) to and from an exterior of the electronic device. The first antenna array (3) comprises a second conductive element (4) comprising a main radiator (4a) of the first antenna array (3), and a plurality of first transmission lines (5) for simultaneously exciting radio frequency range signals to be transmitted between the first conductive element (2) and the second conductive element (4). The transmission lines (5) extend in a common plane through a non-conductive volume (6) located between the first conductive element (2) and the second conductive element (4). The main radiator (4a) is arranged such that it is in direct contact with the exterior. The second conductive element (4) does not block the radio frequency radiation beam transmitted to and received from an exterior of the electronic device, allowing the radiation beam to be steered, at least partially, in any desired direction such that sufficient gain coverage can be achieved in any direction from the beam steering antenna structure.
