A set of integral equations are derived by using the Hankel transform and the two-dimensional Fourier transform. Method of moments is applied to solve these integral equations for the current distribution. The surface electric current on the circular patch is expanded by entire domain basis functions, and the surface magnetic currents on the open-ended slot and the coplanar waveguide are expanded by subsectional linear basis functions. Computed results for the reflection coefficient and the input impedance are obtained which compare favorably with measurements.application/pdf223646 bytesapplication/pdfen-USCircular waveguides; Computational methods; Current density; Electric current distribution; Electric impedance; Electromagnetic wave propagation; Electromagnetic wave reflection; Fourier transforms; Integral equations; Magnetic properties; Method of moments; Substrates; Cavity model; Circular patch antenna; Entire domain basis function; Full-wave analysis; Hankel transform; Magnetic-current density; Open-ended coplanar waveguide; Subsectional linear basis function; Surface magnetic current; Two-dimensional Fourier transform; Microstrip antennasjournal article10.1109/APMC.2001.9853832-s2.0-0035726864http://ntur.lib.ntu.edu.tw/bitstream/246246/2007041910021391/1/00985383.pdf
