Abstract :
A study is made of the resonant frequency of circular microstrip patches. The resonant frequency problem is formulated in terms of an integral equation. Galerkin´s method is used to calculate the resonant frequencies of nonaxial symmetric modes in different circular microstrip patches. Using the database built by Galerkin´s method, a curve-fitting formula is developed to reproduce the accurate resonant frequency rapidly. The accuracy of this formula is within 1.0%. This formula is useful for the computer-aided design of microstrip antennas and microwave integrated circuits.
