W-band piezoelectric transducer-controlled low insertion loss variable phase shifter

A low-cost and low-loss piezoelectric transducer-controlled phase shifter for millimetre-wave/sub-terahertz applications is presented. The proposed idea is based on reducing the propagation constant of a high-resistivity silicon image guide by a high dielectric constant slab loading. The proposed ph...

Zusammenfassung:	A low-cost and low-loss piezoelectric transducer-controlled phase shifter for millimetre-wave/sub-terahertz applications is presented. The proposed idea is based on reducing the propagation constant of a high-resistivity silicon image guide by a high dielectric constant slab loading. The proposed phase shifter has a measured insertion loss of
