dc.description.abstract Merits of planar antennas make them a potential candidate for the field of communication in Microwave application. This thesis presents performance comparison of Coplanar /Micro strip patch Antenna for microwave X-band, S-band and C-band applications using coplanar waveguide feed technique. As coplanar waveguide feeding has wider bandwidth and high radiation efficiency it could be applicable in many X- band, S-band and C- band applications. The substrate applied in the design process for both coplanar and microstrip patch antenna is FR4 Epoxy Glass, which has relative permittivity of 4.4 and substrate height 1.6mm. Antenna measurements such as, bandwidth efficiency, radiation pattern and radiation efficiency are conducted and the performances are compared. Antenna simulations have been performed by using Ansoft HFSS TM V13.0, which is a Finite Element Method (FEM) based electromagnetic solver. Simulation results are presented in terms of Resonant Frequency Return Loss, Radiation Pattern and the antenna Gain. It has been found that microstrip patch antennas have lower return loss and are more directive than coplanar patch antenna. The simulated results have also shown that coplanar patch antennas have high radiation efficiency and comprises of a wider bandwidth as compared to a microstrip patch antennas. The radiation efficiency obtained for microstrip patch antenna ranges from 82.342% to 89.231% and that for coplanar patch antenna is 92.31% to 98.78%. Meanwhile, the directivity for microstrip patch antenna ranges from 5.352dB to 7.65dB and that for a coplanar patch antenna is 2.79dB to 5.69dB. en_US
