Substrate Permittivity Effects on the Performance of the Microstrip Elliptical Patch Antenna

In this paper, the performance of a microstrip elliptical patch antenna is investigated using different substrate materials. The Microstrip antenna is studied with different substrates for a radiating elliptical patch of fixed dimensions. The effects of the dielectric constant of the perfect and lossy substrates on the resonant frequency, bandwidth and gain are investigated. A gain drop of 1.3 dB per decade is observed. Return loss, input impedance, radiation patterns and current distributions are investigated and presented with the help of Ansoft-HFSS.
