The coupling mechanism mainly depends on the shape of aperture , patch and the feed line; it also affects the radiation properties. The paper analyses some of the different shapes of these elements on the aperture coupled microstrip antenna. One effective way to increase the impedance band - width is to change the patch shape, feed sh ape and the slot shape. The shape of coupling aperture has a great effect on the strength of coupling between the feed line and the patch. Mainly thin rectangular shape of the slot is used in an aperture coupled microstrip antenna. If a suitable combinatio n of the shape of feed and slot is chosen and tuned perfectly, it gives an optimum impedance bandwidth with an improved radiation pattern
