Abstract

In this paper, a new design of microstrip patch antenna is consider in which it is insert a p-i-n diode on ground plane of the antenna. Analytically observation has been demonstrated the different parameters i.e. return loss, gain, active vswr, and axial ratio in our designed antennas. Here, a coaxial feed technique has been manipulated for the microstrip patch antenna at 2.4 GHz. The improvement in return loss is -2.287dB has been obtained at 1.98 GHz for ranges the operating frequency from 1.5 to 3.5 GHz. It also has been obtained gain total as 5.7960dB at 1.98 GHz with phi 0 deg and theta 0 deg and VSWR, axial ratio etc. better with conventional antennas. These type antennas has application in the satellite communication, aerospace, radars and biomedical applications etc.
