Abstract
This paper presents design and simulation of a novel microstrip patch antenna in the ultra wide band frequency region (3.1 ⨯ 10.6GHz)and its modified versions with enhanced bandwidth on a FR408 substrate having relative permittivity of 3.75 and thickness of 1.5 mm respectively. The simulated antenna performance was obtained by Computer Simulation Technology Microwave Studio (CST MWS). The antenna performance was investigated by analyzing its return loss (S11), radiation pattern, voltage standing wave ratio (VSWR)parameters. The simulated S11 parameter has shown that antenna operates for Wi-Fi (3.6⨯3.7GHz), WiMAX (3.4⨯3.6, 3.7⨯4.2GHz), and Wireless Local Area Network (WLAN 5.3⨯6.3GHz).
