Abstract: | This paper presents a compact Ultra-Wideband (UWB)band-pass filter using a high-pass filter and a low-pass one,and the resonator with Iumped elements.The structure of our proposed bandpass filter is very simple and the Defected Ground Structure (DGS) structure is used to get the low-pass filter characteristics.This proposed band-pass filter can be much smaller than a cascaded type filter.As a result of simulation,the insertion loss is less than 0.3 dB throughout the pass-band of 2.2 GHz~10.6 GHz,while the return loss is more than 18 dB.And it has rejection level of 36 dB at GPS band. |
