Abstract

In this paper, a fast and efficient method based on MOM is proposed for the analysis of antenna and array mounted on bodies of revolution. An attachment mode is introduced to ensure the continuity of current density at the junction region between wire antenna and cylindrical surface. A method based on suitable changes of coordinates and domains is presented to extract singular point of the self-impedance element calculation at junction region and accurate impedance can be obtained. Taking the antennas and array mounted on a finite solid conducting cylinder as an example, the impedance characteristics and radiation pattern are calculated. The good agreement between the results obtained by using the analysis method presented in this paper and those of CST and NEC software reveals the accuracy and high efficiency of this method.
