Double-layered microstrip, Hairpin-Comb filters, stopband performance, transmission zero, UWB
A new approach for the design of UWB Hairpin- Comb filters is presented. The filters can be designed to possess broad upper stopband characteristics by controlling the overall size of their resonators. The measured frequency characteristics of implemented UWB filters show potential first spurious passbands centered at about six times the fundamental passband center frequencies.
