Abstract
A circular polarized array antenna includes: groups of at least one set of patches for radiating and/or receiving a circular polarised electromagnetic wave; and a network of feeding lines, each feeding line being coupled to and extending longitudinally or vertically to one of the sets for transferring signal energy to and/or from the set. Each of the feeding lines coupled to the sets is pointing into a direction different from the pointing direction of the other feeding lines in order to achieve a circular orientation of the network of feeding lines.
