Abstract

The aim of this research work is to enhance the bandwidth of an octagonal shaped microstrip patch antenna. For this purpose stacking concept has been used. Electromagnetic coupling is provided between the top and bottom patch. The dielectric substrate material of the antenna is glass epoxy FR4 having ?r=4. 4 and loss tangent 0. 025. The performance of the final modified antenna is compared with that of a Rectangular Shaped Microstrip Patch Antenna (RSMPA) and Rhombus Shaped Microstrip Antenna (RSMA). The designed antenna has two resonant frequencies 5. 29 GHz and 5. 49 GHz. So this antenna is applicable for the WiMax application. This electromagnetic coupled antenna offers much improved impedance bandwidth 22. 08%. This is approximately five times higher than that in a RSMPA antenna (Bandwidth = 4. 43%) having the same dimensions.
