Design of L-Shaped Microstrip Patch Antenna

This paper presents study on a microstrip patch antenna, which resembles like English alphabet “L”. The proposed patch antenna resonates at 9.15 GHz with gain and bandwidth of 4 dBi and 1.51 GHz (16.33%), respectively. The directivity of this patch antenna is 8.390 dBi. Coaxial probe feeding has been used to feed the proposed antenna. This operating band of the proposed antenna is beneficial for X-band applications like Earth Exploration Satellite System (EESS), which is used in several areas such as weather forecast, collecting data about the earth etc. 1.6 mm thick FR4 substrate has been used to fabricate this proposed antenna. The proposed antenna possesses low profile and is easy to fabricate. Simulations are done on commercially available electromagnetic simulator, HFSS, which works on the theory of full wave finite element method.
