Circular polarised array antenna

摘要

The present invention relates to a circular polarised array antenna comprising groups (6) of at least one set (10) of patches (2) for radiating and/or receiving a circular polarised electromagnetic wave, a network of feeding lines (3), each feeding line (3) being coupled to and extending longitudinally or vertically to one of the sets (10) for transferring signal energy to and/or from the set (10) whereby each group of feeding lines (3) being coupled to a group (6) of sets (10) is pointing into a direction different from the pointing direction of the other groups of feeding lines (3) in order to achieve a circular orientation of the network of feeding lines (3) and respectively two adjacent groups of feeding lines (3) include the same angle. The invention further relates to a method for executing the steps on the array antenna, to a beam-switching array antenna and to a method for a beam-switching array antenna.
