Improvement of antenna performance using stacked microstrip patch antenna

A rectangular stacked microstrip antenna has been designed in this paper to increase the performance of the conventional microstrip antenna. The antenna performances such as bandwidth, gain, directivity and return loss of the conventional and stacked antenna have been examined using coaxial probe feed and transmission line feed techniques. A comparative study has been also made between these two techniques. The antenna has been designed using ansoft HFSS software to operate in the C-band having resonant frequency 5.3 GHz.
