Abstract

In this contribution, a dual-reflectarray dual-offset antenna is proposed to wide-angle beam scanning applications. An antenna with this configuration is designed and its performances are studied to scan the beam in 16 degree range at 35 GHz. The proposed configuration is derived from a dual-offset dual-reflector bifocal antenna, and the synthesis method of the reflectarrays is also based on a technique reported in previous works for dual-reflector antennas. The dual-reflector antenna is defined and then the equivalent reflectarrays are synthesized. Finally, the entire antenna is analyzed considering each of the two feeds in order to evaluate the performances.
