摘要
A dual-polarized stacked patch antenna array (100) that operates at two different frequencies (320, 330). The stacked patch antenna array {100) has a single planar patch antenna subarray (101, 150) disposed on opposite sides of a dielectric substrate (130). The stacked patch antenna array includes a ground plane (190) that is common to each planar patch array antenna. Each planar patch antenna subarray (101, 150) is fed from a single coaxial probe (180) disposed through the center of the stacked antenna array structure. Each patch (102, 104, 106, 108, 152, 154, 156, 158) in the planar patch array antenna subarray (100) is electrically connected by microstrip elements (101e, 101f, 101g, 101 h, 151a, 151b, 151c, 151d). Each patch and microstrip element is arranged along the X and Y axial directions. A single additional microstrip element (110, 159) is placed in a diagonal orientation in each subarray to connect two patches oppositely oriented within the stacked antenna array structure.
