In this article, a multiport beamforming system based on the reconfigurable waveguide phased antenna array is presented, which is fed by the microstrip single-layer multiport feeding network. The reconfigurable waveguide transitions and waveguide linear-polarized/circular-polarized antenna arrays have high flexibility to meet different requirements in beamforming applications according to the design purposes, which is also suitable for satellite communication applications with separate transmitted and received systems. Both simulated and experimental results are presented for the demonstration. Results indicate that the multiport beamforming system based on the reconfigurable waveguide phased antenna array could provide wideband performance at both K/Ka-band with flexible functions compared with the conventional single-layer beamforming systems.
