Abstract :
A study is made of the resonant frequencies of rectangular and circular microstrip patches to develop their design formulas. The resonant frequency problem of rectangular microstrip patches is formulated using vector Hankel transforms. Both formulations result in integral equations for which Galerkin´s method is used to ascertain the resonant frequencies. The results agree with experiments and asymptotically agree with the perturbation approach. Based on these solutions, the design formulas for the microstrip patches are developed using least-square fits.<>
