Abstract
The invention relates to a circularly polarized array antenna for receiving and transmitting a circularly polarized signal. The circularly polarized array antenna comprises: a plurality of circularly polarized antennas with phase shift mechanism for receiving circularly polarized signals and transmitting the circularly polarized signals; a plurality of power lines which differ from each other in length and are coupled to the circularly polarized antennas respectively; and a power divider coupled to the power lines for receiving the circularly polarized signals. Wherein each of the circularly polarized antennas comprises a plurality of antenna elements and each comprises a microstrip antenna and a slot coupling apparatus.
