Antenna Rotator Design by 3D Printing

Abstract

Due to the problematic availability or expensive purchasing costs of anechoic chamber for antenna parameter measurements, it would be worth considering a design of a low-cost alternative. This paper presents the design and implementation of an antenna platform that could be used for the measurement of basic radiation parameters of low power antennas. The antenna platform is manufactured by 3D printing. The aim of this paper is to describe the design and realization of the antenna rotator with focus on high accuracy of position control, variability of possible use (different types of antennas made of different materials) and low cost.
