New expression for the resonance frequency of an E-shaped microstrip patch antenna

Abstract

The resonance frequency of an E-shaped microstrip antenna has been calculated by equating its area to an equivalent area of a rectangular microstrip patch antenna. A new expression for effective dielectric constant is developed for the E-shaped microstrip patch antenna. The new expression of resonance frequency is used to calculate the results, which are in good agreement with the measured and published results. © 2006 Wiley Periodicals, Inc.
