Abstract
A compact, agile polarization diversity, multiband antenna with integrated electronics for satellite communications antenna systems is disclosed. The antenna includes a feed assembly having integrated microwave electronics that are mechanically and electromagnetically coupled thereto in a distributed arrangement so that diverse polarization senses having a low axial ratio and electronic switching control is provided. The microwave electronics include a distributed transmitter that can include high-band and low-band transceivers. The high-band and low-band transceivers can include high-band and low-band transmitter and receiver pairs, respectively. The antenna presented enables the mechanical rotation of the orientation of the high-band transceiver for skew alignment while the low-band transceiver remains stationary relative to the antenna assembly. The low-band transmitter and receiver pair can include planar interfaces electromagnetically coupled to the feed assembly between a main reflector and subreflector via OMTs. The highly compact antenna system presented offers polarization performance previously achievable by only larger devices.
