This paper presents a V slot microstrip patch antenna.In this antenna a V shaped slot cut inside the rectangular patch of the antenna for performing multiband application. This antenna is designed using FR4 epoxy substrate with coaxial feed technique, and simulated on HFSS. The proposed antenna is resonating in S band, C band and X band at frequencies 3.2GHz, 5.5GHz, 8.2GHz and 9.2GHz.The return loss of V slot antenna is 14.4dB, 22.1dB, 23.4dB and 13.2dB and gain is 2.7dB, 4.8dB, 6.6dB and 4.3dB respectively at resonating frequency. The directivity of proposed antenna was maintainedto begreater than 5dB at all resonant frequencies. This V slot microstrip patch antenna is acceptable for today’s communication system.
