W-band circular polarized series fed single plane beamsteering array antenna with 4-bit phase shifter for cubesat applications

Abstract

A 16 × 32 series fed right-hand circular polarized (RHCP) phased array antenna is investigated at 85.4 GHz on a single layer substrate. The broadside patterns show co- and cross-polarization separation of around 18 dB and peak RHCP gain of 30 dBic. A 4-bit phase shifter is also designed in Cadence Virtuoso. The phase shifter states are applied in the simulation of 16 × 32 array to show the beamsteering of +/− 30° in one plane of the series fed array.
