摘要： A switchable polarizer assembly, having a coupler, a polarizer module with a plurality of apertures, each aperture adapted for a desired transition, an antenna adapter and a central waveguide with a center longitudinal axis passing through the coupler and the antenna adapter. Positioned inline with the central waveguide, between the coupler and the antenna adapter, the polarizer module is offset relative to the center longitudinal axis, rotatable to alternatively align each of the plurality of apertures with the central waveguide. A coupling means may be present to couple rotation of the polarizer module to rotation of the antenna adapter. The apertures may be, for example, zero or ninety degree angular transitions and or circular to rectangular waveguide cross sectional area transitions.

摘要： The present invention provides a feed horn for use in an antenna assembly having a non-circular reflector. The feed horn is capable of transmitting and receiving circularly polarized signals. The feed horn includes a circular waveguide section for connection to a transmitter and receiver of the antenna assembly. A conical waveguide section is connected to an opposed end of the circular waveguide section for creating a smooth transition from the circular waveguide section to a non-circular corrugated waveguide section. The corrugated waveguide section includes a plurality of corrugations that transition for a circular shape adjacent to the conical waveguide section to an increasing non-circular shape at an end proximal to the reflector of the antenna assembly. The corrugations have individuals depths defined in the inner wall of the corrugated waveguide section. These depths compensate circularly polarized signals propagating in the feed horn for distortions due to the non-circular reflector.

摘要： There are herein described microwave devices that are mounted at the output ends of circularly polarized horn antennas of a microwave antenna array. The devices act as coupling compensators between the horns, and also function as singular or dual polarization trimmers to create very low axial ratio circularly polarized antenna array patterns through a broad angular range. In each of these devices, a parasitic element is disposed on a planar substrate that is orthogonally positioned with respect to the direction of propagation from the horn antennas.

摘要： A horn antenna is disclosed having a built-in circular polarizer and a cross polarization attenuator. A square-apertured horn antenna has a plurality of pairs of conductive fins disposed along opposite edges of the horn interior. The individual fins are separated from each other by approximately one-fourth wavelength. The fins are at a 45 degree angle to that linear wave and react with that linear wave by imparting a circular rotation to that wave as the wave propagates past each pair of fins. A stepped attenuator is mounted in the input section to the horn antenna perpendicular to the linear input wave. The attenuator substantially absorbs cross-polarized signals whether reflected from the aperture of the horn or provided by the incoming signal.

摘要： A BROADBAND CIRCULARLY POLARIZED ANTENNA HAVING A CONTINUOUS RECTANGULAR APERTURE TO OBTAIN CIRCULAR POLARIZATION, HAVING UNIFORM PHASE AND TAPERED AMPLITUDE ILLUMINATION OVER THE BROAD DIMENSION OF THE APERTURE. THE DEVICE FEATURES A LARGER EFFECTIVE RADIATING OR RECEIVING APERTURE THAN COMPARABLE RECTANGULAR ARRAY OF CIRCULARLY POLARIZED SPIRALS DUR TO THE USE OF VIRTUALLY LOSSLESS RADIATING

ELEMENTS TO PROVIDE HIGHER GAIN. LINEARLY POLARIZED RADIATING ELEMENTS ARE UTILIZED TO FEED AN APERTURE WITH LINEARLY POLARIZED ENERGY WHICH IS THEN TRANSFORMED INTO CIRCULARLY POLARIZED ENERGY BY MEANS OF A POLARIZER GRID.

摘要： Apparatus and methods for circularly polarized antenna arrays are disclosed. In certain embodiments, a dual-band dual-polarized antenna array is provided. The antenna array uses separate frequency bands for transmit and receive signals, and supports a right hand circular polarization (RHCP) and a left hand circular polarization (LHCP). The antenna array can be formed on a circuit board to which a beamforming integrated circuit (IC) can be attached. For example, the antennary array can formed form a low-cost printed circuit board (PCB) stack-up construction. The antenna array can provide circular polarization without needing a polarizer or coupler. Furthermore, the antenna array achieves good isolation and axial ratio under scan.
