Compact 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 کاملA 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 کاملNew Triangle-Ring UWB Bandpass Filter with Sharp Roll-Off and Dual Notched Bands
This paper presents a new ultra-wideband (UWB) bandpass filter (BPF) with sharp roll-off and dual-notched bands. The filter consists of a triangle ring multi-mode resonator (MMR) with the stub-loaded resonator (SLR) for controlling the two transmission zeros at 2.8 / 11 GHz, the embedded open-circuited stub and the asymmetric tight coupled input/output (I/O) lines for introducing the dual notch...
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 UWB Band-Pass Filter with Dual Notched Bands Based on Novel Defected Ground Structures
A compact ultra-wide-band (UWB) band-pass filter (BPF) with dual notch bands is presented using novel defected ground structures (DGS). A couple of triangle-ring resonators with four open-stubs fed by a couple of inter-digital coupled structures is developed to meet the UWB requirement of a uniform 3.1GHz to 10.6GHz full-band transmission response. Dual notch bands are generated for filtering o...
