Comparison of Microstrip Patch Antenna using Different substrate Material for Multiband Application

Abstract

In this article, the comparisons of parameters of S-shaped radiating patch using L-strip feeding for multiband operation. It is proposed that antenna fabricated on foam shows better performance than Bakelite substrate.The antenna is first analyzed using software simulation, and then fabricated on Foam and Bakelite substrates and their characteristics are compared. The resonating modes of S-shaped patch antenna are obtained between 6 GHz to 45 GHz for foam whereas 2 GHz to 20 GHz for Bakelite. The reflection coefficients and bandwidth of both antennas are compared and discussed. The geometry is simulated using commercially available IE3D software and the results are measured and tested. It is found that the agreement between the computed and experimental results was very good.
