Bandwidth reconfigurable microwave bandpass filter

Abstract

Summary form only given, as follows. A design approach for a microwave bandpass filter (BPF) with bandwidth reconfigurability is presented. The proposed design employs varactor-tuned microwave resonators for realization of the bandwidth-reconfigurable BPF. Compared to previously reported design methodology, the presented approach aims for the design of the reconfigurable BPF with relatively wide tuning range as well as low in-band insertion loss.
