Patent number: 11804658Abstract: An apparatus and method for mitigating polarization mismatch in reflector antenna systems. A feed unit is configured to determine a polarization mismatch between a first polarization associated with a first wave and a second polarization associated with a reflector unit. The feed unit pre-distorts the first wave to achieve a compensated polarization for reducing and/or eliminating a polarization mismatch. The pre-distorted first wave having the compensated polarization is used to illuminate the reflector unit. A re-radiated wave is reflected by the reflector unit. Furthermore, the level of the re-radiated wave is increased as a result of the pre-distortion.Type: GrantFiled: November 9, 2018Date of Patent: October 31, 2023Assignee: Hughes Network Systems, LLCInventors: Bingqian Lu, Hamad Alsawaha, Peter Hou, Thomas Jackson

Patent number: 11777618Abstract: Techniques described herein provide phase and amplitude calibration of phased array antennas. In an N-by-M phased array having N*M channels, embodiments use aggregated measurements over multiple concurrently active channels to improve signal-to-leakage performance, while also using sequences of exclusion groups to yield an individualized calibration value for each channel (i.e., N*M individualized calibration values). For example, a J×K channel group of the array is selected in each of a sequence of measurement frames based on a calibration schema. Over J*K measurement sub-frames, a set of J*K aggregate measurements is obtained, each with different subsets of the channel group activated and excluded from the measurement. The aggregate calibration measurements can be used to compute J*K individualized calibration values, each for a channel of the channel group. In some implementations, each calibration value is computed as a complex value including both amplitude and phase calibrations information.Type: GrantFiled: December 27, 2021Date of Patent: October 3, 2023Assignee: Hughes Network Systems, LLCInventors: Xiaoling Huang, Channasandra Ravishankar
