Mode-Matching Model for Electromagnetically Coupled Coaxial Dipole Array Antenna

Abstract

A mode-matching model for an electromagnetically coupled coaxial dipole array antenna is presented. The Fourier transform/series technique is used to represent the continuous and discrete modes of scattered fields. The mode-matching is utilized to constitute a set of simultaneous equations for discrete modal coefficients. Numerical computation is performed to show its radiation behavior in terms of various antenna parameters.
