报告摘要

This presentation introduces recent advances in analogue multi-beamforming networks and antennas for beyond 5G (B5G) and 6G wireless systems. A novel Generalized Joined Coupler (GIC) Matrix is proposed to overcome the inherent limitation of conventional beamforming networks, enabling multiple beams to be steered independently. Both Nolen-like and Blass-like GJC structures are synthesized and optimized using array excitation and radiation pattern-based methods to achieve low sidelobe levels and high flexibility. Several prototypes, including fixed-beams and tunable beams fed by GJC matrices are designed, fabricated, and experimentally verified. The results demonstrate wide-angle, orthogonality, and independently steerable multibeam performance, highlighting the strong potential of GJC-based beamforming networks for compact, high-capacity, and energy-effcient antenna systems in future 6G applications.
