Abstract: In this paper, via hole drilled microstrip patch antenna employing two rectangular slots on patch, FR4 substrate having thickness of 1.6mm and dielectric constant of ?r = 4.4 has been proposed. The proposed antenna has been designed and analysed using Computer Simulation Technology (CST) Microwave Studio 2014. The proposed antenna has compact size, light weight and wide band operation. The via hole slot and rectangular slots have been cut in the proposed antenna in order to increase the return loss and impedance bandwidth of the antenna. The proposed antenna ground and patch has been designed using copper of thickness 0.1mm. It has been analysed that the proposed antenna has an impedance bandwidth of 725MHz with an operating frequency range of 2.6787-3.4038GHz and is resonant at 2.905 GHz. The gain, directivity and return loss of the proposed antenna are 4.52dB,4.011dBi and -72.93dB at resonant frequency of 2.905GHz, respectively. The proposed antenna can be suitably employed for Aeronautical, Weather Radar applications (2700MHZ-2900MHz), Civil and Military applications (2900MHz-3100MHz) and Satellite applications (3100MHz-3300MHz.)
