Abstract

A circularly polarized antenna that includes a plurality of radiating elements configured in a rotationally symmetric pattern, and a feed network connected to the plurality of radiating elements. Each radiating element contains a patch element, and a shorting wall connected to the patch element and adapted to short the same. Unlike traditional sequential-phase feed, which simply relies on the physical length of the delay line to achieve phase progression, the reactance-loaded feed line strategically utilizes the equivalent capacitor and inductor to shift the phase. This method eliminates the reliance on the long delay lines and realizes stable phase differences over a wide bandwidth.
