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
