Abstract

This project represents the design of the microstrip rectangular patch antenna with dual bands frequency at 2.4GHz and 5.4GHz for WLAN application. Jeans has been used as the medium for the substrate. This antenna is low profile with overall size is 23X24 mm. Electronic Band Gap (EBG) structure has been applied to reduce the backward signal and improved the antenna overall gain. Gain of 5.711 dB and 7.474 dB has been achieved for both high and low resonating frequencies respectively, which shows almost 63.7% improvement at low frequency and 121.4% at high frequency. The return loss for the antenna was found to be very little affected by the presence of body which makes the designed antenna to be suitable for wearable communication system applications. Thus, this antenna is suitable for WLAN application purposed especially for medical, consumer electronics sectors and military field.
