摘要： An antenna arrangement (1) comprising a differential mode antenna (1a) and a common mode antenna (1b), the antenna arrangement (1) comprising an antenna structure (2) comprising one radiating element (3), at least one differential antenna feed (4) configured to induce differential mode currents (I1, I2) in the radiating element (3), and at least one common antenna feed (5) configured to induce common mode currents (I3, I4) in the radiating element (3). The antenna structure (2) is configured to excite a first radiofrequency range and a second radiofrequency range in response to the differential mode currents (I1, I2) and the common mode currents (I3, I4). The antenna arrangement (1) further comprises at least one first antenna element (6) operably coupled to the differential antenna feed (4), such that the differential mode antenna (1a) is formed, and at least one second antenna element (7) operably coupled to the common antenna feed (5), such that the common mode antenna (1b) is formed,. The first antenna element (6) and the second antenna element (7) are configured to excite a third radiofrequency range in response to the differential mode currents (I1, I2) and/or the common mode currents (I3, I4). This arrangement makes it possible to locate two antennas in the same given volume while maintaining a high level of isolation between the antennas.

摘要： A radiation field beam steering arrangement (1) comprising a first conductive element (12), a second conductive element (2) extending adjacent the first conductive element (12) and 5 comprising at least one dielectric coupling structure (3), and at least one end-fire antenna element (4). The end-fire antenna element (4) comprises an antenna radiator (5) configured to generate a radiation field having a main beam direction (D0) oriented parallel to a main plane (P1) of the first conductive element (12). The dielectric coupling structure (3) is configured such that a dielectric gap (13) is formed between the first conductive element (12) and a surface 10 of the second conductive element (2), which gap is transparent to radiation having frequencies within in the millimeter-wave frequency band. Optionally, the overlap between the first conductive element (12) and the second conductive element (2) is small enough to not prevent radiation from passing through the dielectric gap (13).

摘要： An antenna comprises an electrically conductive ground plane (401, 505, 608, 701, 801, 901) that defines a first plane and has a first edge (402, 507, 903, 1505). An electrically conductive first ground plate (403, 501, 502, 605, 606, 702, 802, 803, 904) is located on a second plane parallel to said first plane and displaced by a first distance from said first plane. Said first ground plate has a second edge (404, 906) parallel to said first edge (402, 507, 903, 1505) of the ground plane (401, 505, 608, 701, 801, 901). An electrically conductive bridge (406, 607, 703, 807, 907) connects said second edge (404, 906) of the first ground plate (403, 501, 502, 605, 606, 702, 802, 803, 904) to said first edge (402, 507, 903, 1505) of the ground plane (401, 505, 608, 701, 801, 901). An elongated first slot (407, 503, 504, 601, 602, 704, 908, 1501) is delimited by at least one of said ground plane (401, 505, 608, 701, 801, 901) and said bridge (406, 607, 703, 807, 907). The longitudinal direction of said first slot (407, 503, 504, 601, 602, 704, 908, 1501) is parallel to said first edge (402, 507, 903, 1505). Said first slot (407, 503, 504, 601, 602, 704, 908, 1501) is coincident with said first ground plate (403, 501, 502, 605, 606, 702, 802, 904) seen from a direction (405, 909) perpendicular to said first and second planes. A first antenna feed point (408, 603, 604, 705, 910) is on the distal side of said first slot (407, 503, 504, 601, 602, 704, 908, 1501) seen from the center of said ground plane (401, 505, 608, 701, 801, 901).
