摘要

In this paper, a dual-band and dual-polarized electrically tunable reconfigurable reflectarray antenna (RRA) is proposed, fabricated and measured for the beam-scanning performance. The RRA element, a single layer structure with two split-rings and a pair of varactor diodes, can be electrically tuned to work at the two orthogonal polarization modes of the incident electric field at 4.2GHz and 6.5GHz, respectively. Besides, the range of the phase compensation of the element is over 300 degrees at the two polarization modes. Then, a RRA with 15x15 elements is designed, fabricated and measured to prove the validity. The main beam direction can be controlled by tuning these varactor diodes of the RRA and the beam-scanning range is from -60 degrees to 60 degrees. The experimental results and simulation results are in good agreement to prove the correctness and feasibility of the design of the novel dual-band and dual-polarized electrically tunable RRA.
