Abstract :
A reconfigurable double-slug impedance tuner has been developed based on a distributed RF-MEMS transmission line (DMTL). The fabricated device shows very good tuning operation from 10-30 GHz with a capacitance ratio of 2.5:1 resulting in uniform coverage of the Smith chart with a maximum VSWR of 4:1. The simulated and measured results are presented in the paper.
