Abstract :
The paper describes the design of high performance low sidelobe, subarray scannable, circularly polarized microstrip antenna arrays for applications in point to point communications with the NASA ACT satellite (30 GHz transmit and 20 GHz receive). The radiating element and the feed structure are discussed in particular.<>
