Investigation of Dielectric Coated Personal Communication Systems (PCS) Antennas to Meet Modern Claims of Electromagnetic Compatibility (EMC)

A new design of 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 spacial shape of metallic part provides matching with feeding cable and dielectric layer keeps antenna size small. Two types of PSMA are considered: (1) axisymmetric PSMA that provides uniform radiation and (2) directional PSMA. Investigated the user body interaction with the antenna radiated field. The method of auxiliary sources (MAS) is used to study both types of PSMA. Experimental data is provided for several PSMA configurations to validate the MAS results.
