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...

In this paper, a compact band-notched UWB planar antenna with Transmission-Line-fed is presented and I’m using a new technique by etching a narrowband resonance H-shape slot in the ground plane of the antenna. This antenna is capable reducing the interference at the WLAN bands by eliminating the 4.85–6.17 GHz band. The proposed antenna has compact size of 16 × 22 mm2 including the ground plane ...

A closely spaced dual-band notched UWB MIMO antenna is proposed in this paper. A traditional semi-circular monopole with ultra-wideband operation is chosen as an element of the proposed MIMO antenna. When two of the UWB monopoles are put together closely, the mutual coupling between them is apparently strong. To reduce the coupling between the antenna elements, a T-shaped branch is inserted bet...

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...

In this paper, Ultra-Wideband Multi-Input-Multi-Output (UWB-MIMO) antenna with band-notched features is introduced. The band notch of the designed by inserting T-strip into radiating patch to eliminate interference WiMAX applications from 3 4 GHz. To improve isolation and diversity between radiators, radiators are arranged orthogonally decoupling structure added them. proposed has a compact siz...

Abstract— A simple and compact ultra-wideband (UWB) antenna integrated with dual band-notched and desirable gain characteristics is presented in this article. The proposed antenna consists of a rectangular-shaped radiator with a partial ground plane and fed by a 50 Ω microstrip line. By inserting two altered H-shaped slots on the proposed radiator, dual band-notch are created to eliminate the w...

This paper investigates an ultra-wideband (UWB) antenna with a triple-rectangular notch band at 5G, WLAN, and Satellite downlink bands. The 5G WLAN bands are notched by using pair of electromagnetic bandgap (EBG) structures while the satellite is two split-ring resonators (SRRs). EBG structure metallic conductor loaded on backside radiator which connected to patch via shorting pin. SRRs consist...
