High Data Rate Ka-band Beam Switching Antenna Network for Intelligent Satellite Communications

This research paper presents an innovative and compact multi-port transceiver designed specifically for time division duplex (TDD) beam switching antenna networks, with a primary focus on high bandwidth and high data rate applications within the Ka-band satellite communication spectrum. The core innovation of this transceiver lies in its seamless integration of both uplink and downlink transmissions within a single six-port junction. This integration not only simplifies the overall system architecture but also enhances the efficiency of bidirectional communication. To validate the transceiver’s capabilities, extensive simulations were conducted using various PSK/QAM signal modulations, all operating within the challenging 28 GHz frequency band. These simulations aimed to assess the performance of both the multiport modulator and demodulator. The outcomes of these simulations unequivocally demonstrate the outstanding performance of the proposed multi-port transceiver. They further underscore the successful implementation of TDD beam switching antenna networks tailored for advanced satellite communication systems operating in the Ka-band. This breakthrough offers promising prospects for high-speed, high-capacity satellite data transmission in the near future.
