A Compact UWB Bandpass Filter with High Selectivity and Dual Notched-Band
A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...
متن کاملCompact Microstrip Uwb Bandpass Filter with Triple-notched Bands
A new microstrip ultra-wideband (UWB) bandpass filter (BPF) with triple-notched bands is presented in this paper. The circuit topology and its corresponding electrical parameters of the initial microstrip UWB BPF are desired by a variation of genetic algorithm (VGA). Then, triple-notched bands inside the UWB passband are implemented by coupling a square ring short stub loaded resonator (SRSSLR)...
متن کاملCompact Frequency Reconfigurable Microstrip Antenna with Controllable Band- Notched Performance for UWB Application
In this paper, a new design of a frequency reconfigurable microstrip antenna by using microstrip line feeding for UWB applications is presented. The process of frequency band rejection is done through the slots on the radiation patch and ground plane of antenna. Also the antenna bandwidth has been improved by using partial Defected Ground Structure (DGS). Then by putting two switches on the gro...
متن کاملNotched UWB bandpass filter using complementary single split ring resonator
In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...
متن کاملCompact Notched Ultra-wideband Bandpass Filter with Improved Out-of-band Perfor-
In this paper, a compact notched ultra-wideband (UWB) bandpass filter with improved out-of-band performance using quasi electromagnetic bandgap (EBG) structure is proposed. Firstly, a UWB bandpass filter based on a stepped-impedance stub-loaded resonator (SISLR) is combined with quasi-EBG structures, which suppress the undesired spurious bands to improve the out-of-band performance. In order to...
