  • Dual-frequency patch antennas
    Patent number: 10193231
    Abstract: A dual-frequency patch antenna includes a first conductive element configured to receive global navigation satellite system (GNSS) signals at a first frequency band, a second conductive element configured to receive GNSS signals at a second frequency band, and a ground plane. A first dielectric material is disposed between the first conductive element and the second conductive element, and a second dielectric material disposed between the second conductive element and the ground plane. The second dielectric material has a topside with an area at least as large as the topside of the ground plane.
    Type: Grant
