摘要
Abstract
A novel beam-steering antenna is proposed. The radiation element of the antenna is implemented by the metamaterial structure loaded with capacitor, which can reduce the length by 76% compared with the conventional radiation element of the waveguide slot antenna. The antenna is fabricated by Printed Circuit Board(PCB) of Rogers RT5880 and waveguide. The PCB with etched metamaterial elements is used as the antenna radiation surface. The beam direction can be controlled by changing loaded capacitor. Measured antenna patterns show a good agreement with theoretical predictions. This prototype demonstrates the antenna operates at 15 GHz. The peak gain is 11 dBi. The radiation efficiency is 80.8%. The beam-steering antenna achieves seven beam angles, including -28°, -20°, -12°, -6°, 6°, 13° and 24°.关键词
