Abstract

Solution of inverse problem for Pear-Shaped Monopole Antenna (PSMA) for Personal Communication Systems (PCS) is proposed together with a user-friendly program package. Antennas with dielectric coatings are numerically and experimentally studied. The proposed antenna utilizes the advantages of the simple design to match antenna structure with feeding cable and free space. PSMA contains a pear-shaped metallic core covered by a thin dielectric layer. A special shape of metallic part provides matching with feeding cable and dielectric layer keeps antenna size small. Influence of Antenna radiated field on the user body is investigated. The Method of Auxiliary Sources (MAS) and Finite Difference Time Domain Method (FDTD) are used to study mentioned problems.
