Microstrip patch antenna for IEEE 802.11a WLAN (5.25 GHz) application

Abstract

This paper presents a simple rectangular microstrip patch antenna for 5.25 GHz IEEE 802.11. The proposed antenna is designed on Roger TMM 3 substrate with dielectric constant 3.25 and thickness of 2.4 mm. The size of antenna is compact with patch dimension 14 × 16 mm2. The antenna parameters such as return loss, VSWR, gain, and directivity are simulated and optimized using commercial computer simulation technology microwave studio (CST MWS). The return loss is about –17 dB, gain is 7.9 dB, directivity is 6.3 dBi, and VSWR is 1.27 at the operating frequency 5.25 GHz. The main advantage of this antenna is that the designed structure is very simple compared to other proposed WLAN antennas and the cost for making this antenna is also low.
