ANTENNA RADIATION PATTERN CONTROL BASED ON 3D PRINTED DESIGN

Dielectric materials have been applied in modifying the antenna radiation pattern, but it is usually limited to single-beam applications. The goal of this paper is to present a novel methodology to control the antenna radiation pattern based on 3D printing technology. 3D printing enables arbitrary dielectric distribution at different locations. As a result, different radiation patterns can be realized by loading an optimized dielectric material with varied permittivity. In this work, we propose a design of a quarter-wavelength monopole antenna surrounded by a low-profile 3D-printed polymer structure with an optimized dielectric distribution. Unlike the conventional omnidirectional pattern of the monopole antenna, singlebeam and multiple-beam patterns are achieved using genetic algorithm (GA) optimization.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
