摘要: In this paper, a compact ultra-wideband (UWB) bandpass filter with wide notch base on the hybrid microstrip/coplanar waveguide (CPW) scheme, defected microstrip array (DMA), and corner scheme (DCS) is proposed. First, UWB operation employed using microstrip/CPW scheme. Secondly, DMA introduced to achieve in passband, which could cancel interferences (i.e., total 5-GHz band WLAN signals). Thirdly, DCS embedded CPW further improve passband flatness return loss level. Then, implemented, has merits of good frequency responses, 3-dB bandwidth from 5.1 up 5.9 GHz, size.
