Rectangular Microstrip Patch Antenna Using Air as Substrate for S-Band Communication


A Rectangular Microstrip Patch Antenna model is proposed using air as a substrate to study the characteristics of designed antenna. The dimensions of designed antenna are 17 mm × 16.66 mm with substrate at frequency 3.525 GHz. In this paper, the simulation is performed by using software Computer Simulation Technology (CST) Microwave studio based on finite difference time domain technique. The characterization of the designed antenna was analyzed in terms of return loss, bandwidth, directivity, gain, radiation pattern, VSWR.
