摘要： Methods and apparatus for a directive, instantaneous wide bandwidth antenna including a ground plane having a recess with a tapered region accessible by an electromagnetic field via a radiating aperture at a forward end of the recess. The dielectric feed can have a tapered portion proximate the tapered region to guide the electromagnetic field into the recess through the radiating aperture and influence pattern directivity. The antenna can further include a conductive plating disposed at least partially about the dielectric feed in a wedge configuration to influence pattern beam width. The dielectric feed can include a conductive portion on a bottom of the wedge coupled to the conductive plating and to a grooved trace.

摘要： A dielectric resonator antenna (DRA) array having an array feeding network and a parasitic patch array made up of individual antenna elements is provided with a dielectric lens made from a single piece of dielectric material in the form of a generally planar sheet. The sheet may be substantially coextensive with the DRA array so as to cover all of the antenna elements. The single piece of dielectric material has a plurality of dielectric portions defined by a plurality of holes through the sheet. Each dielectric portion may be positioned over one of the antenna elements. Adjacent dielectric portions are connected to each other along connecting edge portions thereof, and a single hole is defined through the sheet between connecting edge portions of a group of mutually adjacent dielectric portions.

摘要： A phase shifter includes a cavity (100) and a first fixed transmission line (301), a second fixed transmission line (302), and a slidable transmission line (201) that are located in the cavity (100). The first fixed transmission line (301) is provided with a first open slot (3011), the second fixed transmission line (302) is provided with a second open slot (3021), and opening directions of the first open slot (3011) and the second open slot (3021) are opposite to each other. Two ends of the slidable transmission line (201) are respectively clamped in the first open slot (3011) and the second open slot (3021), so that the slidable transmission line (201) is electrically connected to the first fixed transmission line (301) and the second fixed transmission line (302). The slidable transmission line (201) slides relative to the first fixed transmission line (301) and the second fixed transmission line (302). In the phase shifter, the slidable transmission line and the fixed transmission lines can be coupled to each other effectively. The phase shifter has a simple structure, and has a low requirement for a transmission device.

摘要： The invention relates to an improved antenna system and antenna module incorporating same. The antenna system comprises a first antenna element adapted to a first frequency band and a second antenna element adapted to a second frequency band. The radiation pattern of the second antenna is improved because the first antenna element comprises: a radiating structure provided on a first side of a dielectric substrate, and at least one resonant structure provided, at least in part, on a second, reverse side of the dielectric substrate. The at least one resonant structure is an open-loop type resonator adapted to resonate at a frequency in the second frequency band. The at least one resonant structure is provided at close proximity to the radiating structure on the reverse sides of the dielectric substrate, occupying, on the second side of the dielectric substrate, an area which is only in part covered by the radiating structure on the first side of the dielectric substrate.

摘要： Arrays of low permittivity Polymer-based Resonator Antenna elements with different configurations. Individual array elements can be fabricated with complicated geometries; these elements can be assembled into complicated patterns as a single monolithic fabricated structure using narrow wall connecting structures, which removes the requirement to position and assemble the array elements. Monolithic array structures can be assembled as sub-arrays in larger array structures. Elements, sub-arrays, and arrays can also be formed by inserting dielectric materials into cavities defining their lateral geometries, and fabricated in polymer templates. The polymer templates can be removed or retained to function as part of the antenna. Effective excitation is achieved by one of a number of coupling methods, including standing metal strip feeding on the vertical sides of the elements, feeding by tall metal transmission lines in contact or in close proximity to the vertical sides of the elements, modified microstrip feeding, or aperture feeding by using a slot in the metal plane underneath the elements. The wideband array feeds are realized by optimized transmission line distribution networks which include wideband matching sections.

摘要： The invention relates to the size reduction of an antenna using a magneto-dielectric material for a CRLH-TL (Composite Right/Left Handed Transmission Line) antenna. In particular, the invention provides a small and low profile metamaterial antenna attained by performing SRR (Split Ring Resonator) magnetization on a dielectric material and applying the magneto-dielectric material to the CRLH-TL antenna that is composed of patches and vias. Even further, the invention provides a metamaterial antenna using a magneto-dielectric material, the antenna comprising: a substrate which is made up of a magneto-dielectric material and which has an SRR structure inserted thereto; patches with a CRLH-TL structure formed at a predetermined distance above the substrate; and a ground plane formed at a predetermined distance below the substrate.
