Performance Enhancement of Rectangular Microstrip Antenna with Different Substrate Materials.

Abstract

 Abstract: Above 1GHz , Microstrip antenna is extensively used in Wireless communication. The demand of increased wireless communication applications, needs increase in bandwidth, gain and efficiency of microostrip antenna. Microstrip antenna is a low profile antenna but has narrow bandwidth, low gain and efficiency. In this paper amicrostrip antenna is designed with dimensional change technique to improve bandwidth, gain and efficiency. The enhanced performance of proposed design with different dielectric materials designed and are compared with reference Microstrip antenna. A bandwidth enhancement of 230MHz and gain enhancement of 8.4dB are achieved with proposed antenna.
