Bandwidth enhancement of rectangular microstrip patch antenna using slots

Abstract

In this paper, a new design of rectangular microstrip patch antenna (RMPA) without slot, with slots and array is proposed and analyzed.The designed antenna has been simulated using HFSS software.The simulated results for return loss, radiation pattern and gain are presented and discussed.The bandwidth of proposed antenna is 2.4GHz-5.9GHzfor VSWR(voltage standing wave ratio)<2 is achieved on the basis of <-10dB return loss as an acceptable reference in wireless applications which cover worldwide interoperability for microwave access (WiMAX) and wireless local area network (WLAN) and other applications.Gain of 10dB is achieved for antenna array.
