Abstract

In this paper design of microstrip line fed three step stairs with T shape notch wideband antenna for wireless applications is proposed. This antenna operates in single wideband frequency ranging from 3.36GHz to7.15GHz covering WLAN bands and WiMAX applications with a total bandwidth of 3.8GHz. Effects of varying the dimension of T notch on the antenna performance have been studied. This compact antenna fed by 50ohm microstrip line is low profile and very easy to manufacture.
