Abstract:
A new multi-layer planar array architecture to achieve multi-polarized radiation is developed in this paper. The design concept is based on embedding U-shaped coupling slots in the ground plane to extend the bandwidth. The proposed antennas have two feed ports, by adjusting the feeding properly, the antennas can transmit arbitrary elliptic polarized signal theoretically. Return loss and radiation patterns are measured for the 1-element, 2-element, 4- element, 16-element antenna arrays at 12.5 GHz. Radiation patterns of the antenna arrays show close agreement to the predicted ones in the shape of the main beam. By further incorporating properly designed feed networks, the -20 dB return-loss bandwidth of the proposed antenna arrays can cover the 12.5 GHz frequency band (12.25-12.75 GHz). Design details and experimental results are presented and discussed.
