A 2×2 Dynamic Polarization-Controlling integrated phased array
Radiator arrays with Dynamic Polarization Control (DPC) and 2D beam steering enable polarization matching to the receiver antenna regardless of its polarization, orientation, and location. A fully integrated 122.9 GHz 2×2 DPC multi-port driven phased array radiates all linear polarizations (0°–180° polarization angles) with axial ratios above 14 dB, and controls the axial ratio from 1.2 dB (circular) to 17.8 dB (linear) with a maximum EIRP of +12.3 dBm and 2D beam steering of up to 15°.
