Abstract
An exemplary embodiment of the present disclosure provides a dual-feed dual-polarization high directivity array antenna system. The dual-feed dual-polarization high directivity array antenna system comprises a substrate, a first array radiating group, a second array radiating group, a third array radiating group, a first feed network, and a second feed network. The first feed network is electrically connected to the first and second array radiating groups for inputting a first signal to the first and second array radiating groups. The second feed network is electrically connected to the second and third array radiating groups for inputting a second signal to the second and third array radiating groups. The feed directions of the first and second feed networks are perpendicular to each other. Accordingly, the array antenna system can provide orthogonal feed signals. The array antenna system also has the advantages of high isolation, dual polarization and high gain.
