The Influence of a Circular-Patch Monopole Antennas Excitation Method on Their Integral Characteristics

Abstract

Purpose: The question of the influence of modes of excitation of disk monopole antennas of microstrip topology on the antenna general properties is considered. The purpose of work consists in determination of the optimum method of antenna excitation for increasing the antenna matching level with the external microwave chains and its influence on the antenna energy characteristics. Design/methodology/approach: The modeling of antenna general properties is made by using the finite element method (FEM). The modeling is carried out within the model of a half-open resonator formed by the two metal surfaces (a grounded base and just a strip conductor), on which the condition of electric wall is fulfilled, and also by the cylindrical surface on which the condition
