  • Low profile dual frequency magnetic radiator for little low earth orbit satellite communication system
    Patent number: 6069589
    Abstract: A dual-frequency antenna (100) includes a transmit element (110) that is substantially planar and that is formed from a conductive material, such as aluminum, having a loaded slot (140) formed therethrough for transmission of first radio frequencies. The antenna (100) also includes a receive element (115) that is substantially planar and that is also formed from a conductive material having a loaded slot (155) formed therethrough for reception of second radio frequencies. The transmit and receive elements (110, 115) are mounted in a single plane adjacent to a ground plane (105) that is held only a small distance from the transmit and receive elements (110, 115). Preferably, the height of the antenna (100), i.e., the distance between the transmit and receive elements (110, 115), and the ground plane (105) is equal to or less than about 1.4 centimeters for low-profile mounting on truck-drawn trailers.
