Abstract
This paper presents a new configuration of digital phase shifters integrated into WR-12 waveguide. The proposed configuration is based on a bilateral finline bandpass filter associated to MEMS elements as switches and operates at 77 GHz. The phase states are controlled by changing MEMS states integrated in the finline slot. The model described in the paper takes into account all technological constrains (including biasing) and material properties.
