  • Wideband dual-polarized patch antenna
    Patent number: 10044111
    Abstract: A wideband dual-polarized patch antenna includes a ground plane layer and a first dielectric substrate layer disposed on the ground plane layer. A first radiator patch is disposed on the first dielectric substrate layer and a second dielectric substrate layer is disposed on the first radiator patch. A second radiator patch is disposed on the second dielectric substrate layer and a third dielectric substrate layer is disposed on the second radiator patch. A third radiator patch is disposed on the third dielectric substrate layer. The patch antenna also includes first and second feed lines electrically connected to the radiator patches and to the ground plane. The first and second feed lines are configured to excite the antenna in two separate directions to cause orthogonal dual-polarization. The radiator patches and the ground plane are comprised of a conductive material.
