A Performance Analysis of MSA using Various Excitation Techniques

R.Malathy, R.Maheswari

Micro strip antennas (MSA) in antenna technology appeared relatively late, but in recent years has been a very large development of the design of these antennas and the huge interest in their capabilities. MSA has more advantages and better prospects. This paper describes various excitation techniques and performance of different parameters. Performance of the antenna mainly depends on the dielectric constant or permittivity of a substrate .The substrate which has a low dielectric constant will give better performance than the substrate which has a high dielectric constant. Loss tangent or dissipation factor also plays a part in antenna performance. Substrate materials play an important role in antenna design, production and finished product performance This survey suggest dielectric material like Air, RTduroid, Benzocyclobuten and Taconic TLC can be used to fabricate micro strip patch antenna in order to give better performance.
