摘要

本文提出了一种基于全息理论的波束可控天线。固定模式全息图由金属条涂层在聚甲基丙烯酸甲酯(PMMA)板上制成。表面波发射器产生参考波;特别是,具有波束导向能力。该天线主波束可从- 19°转向+19°,指向性在13.85 ~ 16.93 dBi之间变化;工作频率为3.4 GHz ~ 3.6 GHz。

A Beam-steerable Holographic Antenna
This work presents a beam-steerable antenna that is based on the holographic theory. The fixed-pattern hologram is made of metal strips coat on a polymethyl methacrylate (PMMA) slab. A surface-wave launcher generate the reference wave; in particular, with the beam-steering capability. Such an antenna can steer its main beam from −19° to +19° with the directivity varying between 13.85 and 16.93 dBi; the operating frequency ranges from 3.4 GHz to 3.6 GHz.
