Design and Performance Analysis of Microstrip Patch Antenna for Ultra Wide Band Application

Abstract

The study of microstrip patch antennas has made great progress in recent years. Compared with conventional antennas, microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the microstrip patch antennas can provide dual polarization (circular and linear polarizations), dual-band operation, frequency agility, broad band-width, feedline flexibility, beam scanning omni directional patterning. In this thesis we investigated the performance of an inset-feed microstrip patch antenna. It is found that the percentage bandwidth of the designed antenna is 3.4% with a realized gain of 3.95dB and VSWR of 1.096. These results are comparable even better compared with those found in literature.
