BROADBAND PHASED ARRAY WITH A RADIATION FIELD OF CIRCULAR POLARIZATION

摘要

A broadband phased array with a radiation field of circular polarization consists of circular radiators located at the corners of square above a screen, a power distribution circuit and a phase changer. To form required excitation mode of radiators in array, supply points of spirals are located at square sides, when move clockwise along square. Spiral radiators must excite with phases 0°, 90°, 180°, 270°, when move clockwise along array.
