Study and Design of Microstrip Antenna

This paper is about the theoretical and practical study of Microstrip antennas. In the paper we have simulated the results of two rectangular microstrip patch antenna and fabricated them into a single patch that works on multi frequency operations. For the same we have taken two antennas of frequency 9 GHz and 5.67 GHz and impedance matching is done at 50ohm. The feed is coaxial feed with corner excitation The antennas after being rearranged with corner excitation is investigated for operating frequency, return loss and radiation pattern. The rearranged structure shows reduction in resonant frequency. the pattern of radiation seems to be almost same. The frequency of the rearranged antenna is perceived to have increased from before. The whole simulation work is done on HFSS software.
