  • Patent number: 11902001
    Abstract: A system and method for selecting antenna panels for communicating with satellites. The receive panels directed towards a location in the sky where the satellite is expected to be. When the signal from the satellite is received by the panels, parameters of the signals are checked against a threshold. All the panels having the parameters above the threshold are grouped together as a receive group. The parameters of the signals at the receive groups are compared to determine the best receive panel, and the transmit panel associate with the receive panel is selected as the transmit panel.

  • Patent number: 11728577
    Abstract: An array antenna is provided with a plurality of radiating patches, wherein each of the patches, operates in one frequency band along one direction and in a different frequency band along a second direction orthogonal to the first direction. The signals from each radiating patch are coupled to two delay lines, which traverse over a variable dielectric constant plate. A voltage potential is controllably applied to each delay line to change the dielectric constant of the VDC plate in the vicinity of that delay line, thereby introducing delay in signal travel. In order to isolate the voltage potential from the two orthogonal delay lines applied to each radiating patch, at least one of the delay lines is connected to a coupling patch, which capacitively couples the RF energy to the radiating patch.

  • Patent number: 11715876
    Abstract: A system having a platform upon which several phased antenna arrays are mounted and which can communicate with satellites. The system includes a switch that can connect any of the phased array antennas to any of available modems. The system further includes a router that can connect any of the modems to any available computing devices. Based on parameters such as data rates, signal strength, and account information, one or more communication paths are selected for a computing device requesting to communicate with a satellite. Each communication path is established by operating the switch to connect a selected antenna to a selected modem, and operating the router to transfer data between the computing device and the selected modem.

  • Patent number: 11101559
    Abstract: Receive diversity combining uses signals received at multiple antennas and combine them to obtain a higher overall signal to noise ratio. Multi-level ranking is employed to determine the weight assigned to each channel and, once the channels are weighted the weighted signals are added together. In a two-level example the first level ranks the signals according to fidelity of the signal. This is done by calculating cross correlation coefficients, where highest coefficient indicates best fidelity. The second level ranks the channels according to peak to average power ratio. The lowest value indicates the best channel. The two rankings are combined to generate the weight coefficient for each channel prior to combining the signals from all the channels.

  • Patent number: 10741921
    Abstract: A multi-layer software controlled antenna. A radiating patch is provided over a variable dielectric constant (VDC) plate. Variable DC potential is applied across the VDC plate to control the effective dielectric constant at various locations of the VDC plate. RF signal is coupled between a feed patch and a delay line, and the delay line couples the RF signal to the radiating patch. The radiating patch, VDC plate, delay line, and feed patch are each provided at a different layer of the antenna, so as to decouple the RF and DC signal paths. A controller executes a software program to thereby control the variable DC potential applied across the VDC plate, thereby controlling the operational characteristics of the antenna.

  • Patent number: 10700426
    Abstract: An antenna array is steered electronically by controlling the transmission speed of the RF signal in feed line of each radiator in the array. The transmission speed is controlled using phase shifters, that include variable dielectric constant (VDC) material causing the change in transmission speed. The control signal applied to the VDC material generates the required phase shift. The control signal is calculated for each phase shifter in real time for each control cycle, so as to enable the main beam to track a target, such as a satellite. The control signal is a square wave signal, and each control signal has a specifically calculated duty cycle or frequency to generate the required phase shift.
