UWB PRINTED SLOT ANTENNA WITH DUAL NOTCH BANDS

Abstract

UWB printed slot antenna is a vital use these days for the commercial applications. The UWB slot antenna,
covering 3.1–11 GHz, is in the shape of an octagon and is fed by a rectangular patch with a bevelled bottom edge [1].
This paper will present the simulation analysis of slot antennas using different frequencies for bandwidths enhancement.
Used to UWB with dual notch band techniques to solve the problem of antenna bandwidth in mobiles, wireless,
Bluetooth, WI-FI,WI-MAX,W-LAN and broadband etc. These techniques are used to enhance the bandwidt h and
efficiency of antenna. Some approaches for notch bands are introduction of slots in UWB antenna. The effect of notch
band in various antenna parameters like, radiation, efficiency, gain and bandwidth are discussed. Finally the paper
reports a brief description bandwidth enhancement of antenna by using three different frequencies and micro strip feed
line on substrate with a finite size of ground plane .this slot antenna supports 2500MHz , 3500MHz and 5800MHz
frequencies .simulation operations demonstrate that optimum results of antenna and radiation characteristics have been
successfully done for UWB slot antenna.
