Analysis of Printed Antennas Mounted on a Coated Circular Cylinder of Arbitrary Size

An efficient numerical algorithm for the analysis of printed antennas on a dielectric coated circular cylinder is presented. The formulation employs the spectral domain approach. Green's function is evaluated via Olver's uniform asymptotic expansions. The Fourier summation is transformed into integration and the asymptotic part of the integral is evaluated in closed form. The whole procedure results in a numerical algorithm that is at least as accurate and efficient as the respective one for the planar structure. The present approach can be applied for any source-receiver position and any cylinder radius
