- Abstract
This work presents a compact, high performance GaAs V-band bandpass filter (BPF) using a slow-wave coplanar waveguide transmission line (S-CPW TLine) and a CMRC (compact microstrip resonant cell). The slow-wave CPW Tlines have potential for the use in miniaturized low loss compact passive devices in the millimeter-wave frequency band. Owing to strong slow-wave effect, the longitudinal length of the S-CPW is shorter than that of a classical microstrip based on the same technology. The S-CPW TLines in the designed filter were realized with a reconfigurable defected ground structure (DGS). Adding the conventional inductively coupled resonator CMRC BPF allows the resonator to be miniaturized by the exploitation of the transversal dimensions of the CPW, while maintaining its performance as measured by insertion and return losses. However, the DGS cell allows reconfiguration of the structure from a low-band to a high-band BPF. The design of the filters with the DGS using filters that are designed for V-band applications is explained.
