This paper presents bandwidth enhancement of a rectangular microstrip patch antenna which is designed [1][2] for RADAR applications for operating range Ku band. The proposed antenna gives bandwidth of 12.36-16.73GHz for S11__ampersandsignlt;-10dB. The Bandwidth is increased by using square cut and L shape cut on the patch. The antenna is simulated by Ansoft High Frequency structure Simulator (HFSS) software which is finite element method based simulator. After simulation the antenna performance characteristics such as, input impedance, return loss, impedence bandwidth, percentage bandwidth and Voltage Standing Wave Ratio (VSWR) are obtained.
