    • A wireless communication method and antenna system for determining the direction of arrival (DOA) of received signals in azimuth and elevation, (i.e., in three dimensions), to form a beam for transmitting and receiving signals. The system includes two antenna arrays, each having a plurality of antenna elements, two first stage multi-mode-port matrices, at least one second stage multi-mode-port matrix, an azimuth phase detector, an elevation amplitude detector, a plurality of phase shifters and a transceiver. The antenna arrays and the first stage multi-mode-port matrices form a plurality of orthogonal omni-directional modes. Each of the modes has a characteristic phase set. Two of the modes' phases are used to determine DOA in azimuth. The second stage multi-mode-port matrix forms a sum-mode and a difference-mode used to determine the DOA of the received signals in elevation. A beam is formed in the direction of the received signals by adjusting the phase shifters.
    • 一种无线通信方法和天线系统,用于确定方位和高程(即,三维)中的接收信号的到达方向(DOA),以形成用于发送和接收信号的波束。 该系统包括两个天线阵列,每个天线阵列具有多个天线元件,两个第一级多模式端口矩阵,至少一个第二级多模式端口矩阵,方位角相位检测器,仰角振幅检测器,多个 移相器和收发器。 天线阵列和第一级多模端口矩阵形成多个正交全向模式。 每个模式都具有特征相位集合。 两个模式的相位用于确定方位角的DOA。 第二级多模式端口矩阵形成和模式和差模式,用于确定接收信号的高程的DOA。 通过调整移相器在接收信号的方向上形成一个波束。

    • An aircraft in-flight entertainment (IFE) system for an aircraft includes a radome to be carried by the aircraft, and a dual-beam satellite antenna and at least one positioner coupled thereto to be carried by the aircraft and protected by the radome. The dual-beam satellite antenna is to generate dual antenna beams for television programming and Internet data from respective spaced apart satellites. The dual-beam satellite antenna includes a first aperture for receiving the television programming, and a second aperture adjacent the first aperture for receiving the Internet data. A television programming distribution system is to be carried by the aircraft and coupled to the dual-beam satellite antenna to provide television programming within the aircraft. At least one access point is to be carried by the aircraft and coupled to the dual-beam satellite antenna to provide a wireless local area network (WLAN) within the aircraft for the Internet data.
