64-Antenna Array for Circular Polarization with Smoothed Routing Wires and Grounded Square Collar
Authors: ,
Abstract: This paper presents a novel configuration of circular polarization array with 64 unit antennas. A novel configurations of a single antenna is presented first. Then a 4-antenna array is given based on orthogonal arrangement and smoothed routing wire for feeding. Then, 64-antenna array is given by the above 4-antenna and 16-antenna arrays which are settled in four quadrants. Grounded square collar is newly proposed at the peripheral of the array. This collar eliminates cross-sectional radiation and enhances the forward directive gain effectively. Extremely wideband axial ratio and practically enough high gain were first realized in this paper. These characteristics were realized by the innovative technologies found by the authors. And the result of this study was found to be introduced into practical measuring system for detection of position of liquid surface in LNG and oil tankers.
