A Miniaturized Ultra Wideband Slot Antenna with Band Notched Characteristic
نویسنده
چکیده
A Compact planar slot antenna is proposed and developed for Ultra Wideband Applications. The antenna has compact size of 28 x 31 x 0.8 mm 3 . The antenna is fabricated with FR4 substrate and it is fed by Coplanar Wave Guide. The antenna is investigated experimentally to obtain required return loss, gain and radiation pattern characteristics. The antenna operates over a band between 3.1 GHz and 11 GHz for return loss < -10 dB, removing the undesired band of 5.15.85 GHz to avoid interference with WLAN and HIPERLAN/2. The design and analysis of the proposed antenna is made on the method of moments based IE3D Electromagnetic solver. The antenna has stable Omni directional pattern in E-plane and bi-directional radiation pattern in H-plane. The group delay of the antenna is less than 1 ns in operating bandwidth.

An Improved CPW-Fed Printed UWB Antenna With Controllable Band-notched Functions
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...

A design and analysis of a novel proximity-fed printed slot antenna with 3.5/5.5 GHz dual band-notched characteristics are presented. To obtain an ultra-wideband (UWB) response, a circular patch with a rectangular conjunction arm is etched concentrically inside a ground plane aperture. The antenna is proximity-fed by a microstrip line with an open shunt stub on the other side of the substrate. ...

In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...
