摘要: A compact ultra-wideband (UWB) band-pass filter (BPF) with band-notch function is presented in this paper. In the proposed structure defected ground (DGS) and four short-circuited bent stubs are used order to improve performance of reduce size simultaneously. The upper stop-band more than 15dB attenuation level extends 20 GHz. Moreover, a meander-line embedded open-circuited (EOC) stub inside slot on main resonator employed create narrow at WLAN frequencies. measurement results for fabricated UWB BPF good agreement simulation predictions reveals that it satisfies well demands Federal Communications Committee (FCC) 5.5
