Laminar Phased Array with Polarization-Isolated Transmit/Receive Interfaces

摘要

A phased array includes a laminar substrate having both 1) a plurality of elements forming a patch phased array, and 2) a plurality of integrated circuits. Each integrated circuit is configured to control receipt and transmission of signals by the plurality of elements in the patch phased array. The integrated circuits also are configured to operate the phased array at one or more satellite frequencies—to transmit signals to and/or receive signals from a satellite. Each integrated circuit physically couples with one corresponding element so that incoming signals are received by the corresponding element in a first polarization, and outgoing signals are transmitted by the corresponding element in a second polarization. The phased array isolates the transmit signals from the receive signals by orienting the first and second polarizations differently.
