摘要

提出了一种采用超材料透镜的空气耦合贴片天线馈电的法布里-珀罗谐振腔天线。法布里-珀罗谐振器由一个超材料衬底、一层频率选择表面和金属接地面组成的部分反射表面(PRS)组成。在馈电天线上方粘贴两层基板作为透镜，是为了构造双频工作，提高定向性能。说明了附着在FSS上的左手超材料(LHM)衬底的影响。结果表明，在LHM衬底存在的情况下，法布里-珀罗谐振器天线能够在双频下工作，在12.8GHz和13.2GHz时具有较小的电效应和辐射增强

A Dual Frequency Fabry-Perot Antenna Based on Metamaterial Lens

A Fabry-Perot resonator antenna (FPRA) fed by air-coupled patch antenna with metamaterial lens is presented in this paper. The Fabry-Perot resonator consists of a partially reflective surface (PRS) formed by one metamaterial substrate, one layer of frequency selective surface (FSS) and metal ground plane. That two layers of substrate stuck together as lens above the feed antenna is to construct dual frequency working and to enhance the directive performance. The influence of a left-handed metamaterial (LHM) substrate attached to the FSS is illustrated. From the results obtained, it is noted that in the presence of the LHM substrate, the Fabry-Perot resonator antenna is able to work with dual frequency, has an electrically small effect and a radiation enhancement at 12.8GHz and 13.2GHz
