Circular Polarization 16-Antenna Array with Smoothed Routing Wires and Grounded Square Collar
Authors: ,
Abstract: This paper presents a novel configuration of circular polarization 16-antenna array. A novel configurations of a single antenna is presented first. Then a 4-antenna array is given based on orthogonal arrangement and smoothed (S-type) routing wire for feeding. Then, 16-antenna array is given by the above 4-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 axis ratio was first realized 10 times wider than conventional plane antennas. The directive gain also have been enhanced 2.5 dB approximately, which reduces the number of antennas into half for an array.
