In this paper, a new Ultra-Wideband (UWB) Band-Pass Filter (BPF) for UWB applications is presented. The proposed filter is based on ring resonator with inter-digital coupling at both sides. The inter-digital coupling is used to providing strong coupling and to introduce capacitance effect to achieve at pass-band response. To achieve band rejection characteristics L-shaped open stubs are incorpo...

A compact printed wide-slot (PWS) antenna is proposed for UWB applications. The proposed UWB-PWS antenna basically consists of a stepped microstrip feed-line with a rectangular patch stub and a rectangular wide-slot element at the aperture. Additional parasitic split-ring elements are placed along the patch stub to achieve notch-band characteristics. As the proposed antenna in absence of the ri...

In this paper, a compact, planar printed microstrip line fed pentagonal shape ultra-wideband antenna with triple band-notched characteristics is proposed and investigated. By incorporating pair of mirrored Γ-shape, L-shape slots in the patch bent C-shape parasitic strip at backside patch, tunable band notched responses are realized. The fabricated on Rogers RO3003 substrate permittivity 3.0 thi...

An ultra-wideband (UWB) antenna with dual band-notched characteristics is proposed in this letter. The fabricated prototype of the has a compact size 30 × 24 mm which operates at 3 to 14 GHz and attained notch-bands 3.3 3.7 5.15 5.825 GHz. result shows that compact, easy fabricate provides good radiation patterns time-domain behaviours. simulated measured results displayed agreement over entire...
