ABSTRACT
The paper presents an X slot rectangular microstrip patch antenna with quarter wave feed technique that operates in wireless local area network applications. Microstrip antenna with X slot is proposed to achieve circular polarization, reduce the size and widen the bandwidth. The antenna is operated at 3.5 GHz. The impedance bandwidth (VSWR < 2) is 230 MHz and the directive gain is 7.29 dBi. The proposed antenna also provides low return loss (S11=-37.34 dB). The proposed structure is designed and simulated by using Ansoft HFSS software. The simulated results give significant improvement in terms of directive gain and bandwidth.
