Design of Microstrip Patch Antenna Using Defected Microstrip Structure

In this paper, the design of compact size Micro strip patch antenna is presented at resonant frequency 2 GHz using defected micro strip structure which has various wireless communication applications. The antenna is constructed using micro strip feed line technique and fabricated using dielectric FR4 substrate which has dimensions of (35.4 mm×45.6 mm). The frequency response gives a very sharp cut off at 2 GHz with return loss of-31.27dB. The simulation is performed using the commercial Electromagnetic simulation software IE3D 14.1.
