Antenna array for wireless satellite communications with interference mitigation
A recently granted patent (Publication Number: US11881882B2) discloses a wireless, satellite communications terminal featuring an antenna array with multiple antenna elements arranged linearly and spaced equidistantly. The terminal includes phase shifters and signal combiners to process signals received by the antenna elements, generating an interference-mitigated output signal. The complex weights applied by the phase shifters are controlled by two separate controllers - one to model interference and the other to steer the main beam of the antenna array for optimal signal reception. The system is designed to handle RF signals for both transmission and reception, with the ability to minimize signal power and facilitate reception from satellites.
Furthermore, the patent details a method for processing signals by the wireless communications terminal, involving the application of complex weights to received signals to mitigate interference and steer the main beam of the antenna array. The method includes setting complex weights to minimize power in the output signals and to facilitate reception of desired signals, particularly from satellites. The terminal's design incorporates a multi-element antenna array, preliminary signal combiners, phase shifters, and a controller to optimize signal reception and mitigate interference effectively. Overall, the patented technology aims to enhance wireless communication capabilities, especially in satellite communication scenarios, by utilizing advanced signal processing techniques and antenna array configurations.
