摘要： New antenna designs for realizing circularly-polarized antennas with a wide scanning range are disclosed. The designs h are based on arranging four sequentially fed antenna patches to be considered as a single antenna element, referred to as a “super-element,” in the overall phased array. An example super-element includes relatively short transmission lines to provide excitations for the vertically and horizontally polarized fields, with the transmission lines for the vertically and horizontally polarized fields being perpendicular to one other. A parasitic transmission line may be placed around a part of each antenna patch of the super-element to serve as a coupler to further enforce the field vector direction for keeping the circular polarization. With such designs, an axial ratio below 3.6 dB for scanning angles of at least 75 degrees at 39.5 GHz may be achieved.

摘要： This application provides a full-duplex self-interference weakening method and a full-duplex self-interference weakening system. The full-duplex self-interference weakening method includes: separately receiving, by a first port of a dual-polarized receive antenna and a second port of the dual-polarized receive antenna, a signal sent by a transmit antenna; and adjusting and combining the signal received by the first port of the dual-polarized receive antenna and/or the signal received by the second port of the dual-polarized receive antenna, to weaken interference caused by the transmit antenna to the dual-polarized receive antenna. The full-duplex self-interference weakening method and the full-duplex self-interference weakening system provided in this application resolve a problem that a quantity of antennas and an antenna location are limited in an existing antenna interference cancelation method.

摘要： The present disclosure provides a dual-polarized antenna, which is advantageous for a reduction in size by significantly reducing the complexity of a structure while satisfying a Cross Polarization ratio (CPR) characteristic and an isolation characteristic, that is, advantages of a dual feed, by enabling a dual feed using a shift series feed even without another structure in one antenna structure.

摘要： An antenna apparatus includes an antenna integrated with a filter. The antenna apparatus includes a plurality of resonators where at least some of the resonators are each enclosed in a metal cavity and at least one resonator is exposed to free space to form a radiator element. The antenna apparatus has a filter transfer function that is at least partially determined by dimensions of the radiator element and the position of the radiator element within the antenna apparatus.

摘要： A method for producing a dual-polarized antenna includes providing first, second and third dielectric substrates with first and second main surfaces. The method includes patterning a conductive film on the first main surface of the first dielectric substrate to form a first ground conductor having an opening and a metal patch as a radiation element, the patch aligned to the opening in a lamination direction, patterning a conductive film on the first main surface of the second dielectric substrate to form a first feed probe configured to excite the metal patch, patterning a conductive film on the second main surface of the second dielectric substrate to form a second ground conductor having a slot generally parallel to the first feed probe, and patterning a conductive film on the second main surface of the third dielectric substrate to form a second feed probe generally perpendicular to the slot.
