Keywords:
Bandpass filter, compact bandpass filter, defected ground structure, embedded stubAbstract
This paper presents a new configuration of a compact wide-band Bandpass Filter (BPF). The filter is realized using embedded stub configuration along with Defected Ground Structure (DGS) and folded stubs. The proposed configuration not only offers a compact structure but also shows a wide passband and improved out-of-band performance. A prototype model is developed and its characteristics are measured. Good agreement is obtained between simulation and measured results. The results show improved wideband behavior, insertion loss lower than 0.6 dB and 49.16 % of size reduction.
