Abstract :
A novel type of electrically controlled phase shifter has been designed and realized at 35 GHz, by using a piezoelectric bimorph actuator. A figure of merit as high as 270 degrees /0.35 dB has been obtained in the Ka band, as well as an insertion loss of less than 0.5 dB including the mismatch of rectangular to dielectric waveguide transition. Good agreement has been observed between predicted and measured results.<>
