W-Band Phase Shifter Based on Metasurface with Built-In PIN Diodes
摘要
Abstract
A W-band (75–110-GHz) phase shifter was designed and numerically modeled. The phase shifter is a periodic array of rectangular patch antennas on a dielectric substrate with built-in PIN diodes. It was numerically demonstrated that one can achieve a phase shift of the transmitted wave up to 87° at a frequency of 96 GHz with transmittance losses of no more than –7 dB.
