Low-Cost Transmit and Receive Reflectarray Antenna for Satellite Communications in Ka-Band

Abstract

This contribution describes the design of a printed reflectarray to generate a focused beam in dual polarization at 19.7 GHz and also at 29.5 GHz, which are downlink and uplink frequencies for Satcom terminal antennas in Ka-band. The proposed reflectarray allows dual-frequency and dual-polarization operation, as well as simple and low-cost manufacturing. The simulated radiation patterns for a 20-cm reflectarray show a gain better than 30 dBi in both bands, with low levels for cross-polar radiation and side lobes
