Flat-Panel Wideband Dual-Circularly Polarized 8×8 Phased Array Antenna for SATCOM Applications

A wideband, dual-circularly polarized (CP) 8×8 phased array is designed for operation at K-/Ka-band, which exhibits wide impedance and axial ratio (AR) bandwidths that encompass both of the desired satellite communication (SATCOM) bands of 22.55–23.55 GHz and 25.5–27.5 GHz. The array has a scan range of ±50° and ±36° at 23.05 GHz and 26.5 GHz, which are the center frequencies of the two aforementioned bands. The array has been integrated with a beamforming network utilizing 5G silicon RFICs, and the measurement results will be presented during the conference.
