Summary:
Wireless Local Area Network (WLAN) becomes more popular due to its capability to carry high speed signal and low cost. In this system, antenna is important for establishing effective communication between places at different location. Microstrip Slot Antenna has been design and develop based on IEEE 802.11b/g standard in the frequency range of 2.4 GHz ? 2.4835 GHz for WLAN system applications. This paper describes the design of Microstrip Slot Antenna for WLAN application operating at frequency 2.4 GHz. A coaxial feed has been considered for this antenna. Measurement and simulation of return loss and radiation pattern have been presented. Microwave office was introduced as software to simulate and analyze the design of the antenna. Measurement and simulation result have been compared. The result showed, the resonant frequency is shifted forward. The amount of shifted was 6.6 %. Then, the antenna has been redesign based on the shifted frequency in order to achieve the desired frequency for WLAN application. The bandwidth up to 4.82 % has been achieved with cross isolation for both plane > 10dB. The HPBW for E plane is 70? and H plane is 85?.
