Abstract

Closed-form expressions for two kinds of Hankel transform integrals, which are encountered in the spectral moment method solution of a circular patch, are obtained. Application of the newly obtained formulas alleviates dramatically the algebraic work for determining the Hankel transforms of the current basis functions involving Chebyshev polynomials and edge condition. Computed moment method results using these expressions are presented. The effects of both uniaxial anisotropy in the substrate on the resonant frequency and bandwidth are investigated.
