Polarization-Reconfigurable Patch Antenna-On-Package For Millimeter-Wave Operations With Dc Bias Circuit Design

The proposed polarization-reconfigurable antenna is designed for implementation on IC packaging. For verification, we used Rogers R04003C boards which closely resembles the material of PCB with packaging. Our prototype swaps out the switchable PIN diode with copper strip and is measured using a styrofoam rotation platform. With DC block and RF choke present in the design, the measurement results show that the design achieves 3-dB axial ratio with sub--6 dB reflection coefficient at 30 GHz.
