چکیده
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 ground plane slot, reconfigure ability is added to antenna. The antenna dimensions are 20×20 mm2 which is very compact. Simulation results show that the designed antenna is able to cover the frequency range 3.1-10.9 GHz. Also shows a performance of frequency band rejection in the range 5.1–5.9 GHz which is related to WLAN systems. Keyword: Reconfigurable Antenna, WLAN, Band Rejection, UWB.

Multi Attribute Analysis of a Novel Compact UWB Antenna with Via-fed Elements for Dual Band Notch Function (RESEARCH NOTE)
A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...

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 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)...
