V. CONCLUSION
A novel technique for enhancing bandwidth of microstrip
patch antenna is successfully designed in this paper using
HFSS’11. Simulation results of a wideband microstrip patch
antenna covering 8.75 GHz to 11.68 GHz frequency have
been presented. Techniques for microstrip broad banding,
size reduction, and cross polarization reduction are applied
with significant improvement in the design by employing
proposed slotted patch shaped design, aperture coupled
feeding. The proposed microstrip patch antenna achieves a
fractional bandwidth of 29% (8.75 to 11.68 GHz) at -10 dB
return loss. The maximum achievable gain of the antenna is
8.94 dB with gain variation. The proposed patch has a
compact dimension of 10.5 X 12.5 mm.
