我们在场试验性地使用 metamaterials 的一条象 Luneberg 一样圆柱的透镜天线。有宽广带宽的圆柱的透镜天线由非反响的我塑造 metamaterial 结构组成。metamaterial 透镜天线的近地的分布用扫描仪器的二维的近地的微波被测量,并且与模拟结果同意很好。天线的远地的放射模式也被介绍在宽广带宽显示出高获得的表演。
We present a Luneberg-like cylindrical lens antenna experimentally using metamaterials. The cylindrical lens antenna with a broad bandwidth is made up of the non-resonant I-shaped metamaterial structures. The near-field distributions of the metamaterial lens antenna are measured using a two-dimensional near-field microwave scanning apparatus, and agree well with the simulation results. The far-field radiation patterns of the antenna are also presented to show the high-gain performance in the broad bandwidth.
