Microstrip antennas have various advantages especially small size and cost of fabrication of antenna is very less. Because of the above mentioned advantages, microstrip antennas are used in wireless communication systems. But it has drawback of narrow bandwidth. Aperture coupling technique is one which helps to improve this bandwidth up to some extent. Therefore, in this paper this technique has been used. The mathematical model using transmission line and a design at 5.8GHz (WLAN and WIMAX) has also been discussed.
