On the dynamic beamwidth control of partially reflective surface antennas

This paper describes recent findings and results related to the possibility of dynamic beamwidth reconfiguration in partially reflective surface (PRS) antennas. We explore the PRS reflectivity reconfiguration, which is here the key to the directivity and beamwidth dynamic control. Various reconfigurable PRS antennas are studied for applications where linear, circular, and dual-linear polarisation is required. Varactor diodes and RF-MEMS switches are employed to enable the reconfiguration of PRS reflectivity. Finally, simultaneous beam-steering is also achieved here by means of an antenna array feeding the reconfigurable PRS antenna.
