摘要

在本通讯中，我们提出了一种基于近零折射率(NZIM)的增强增益和指向性的超宽带椭圆超材料天线。工作频率范围3.1GHz ~ 20GHz。由于NZIM的有效磁导率和介电常数被优化为同步趋近于零，使得NZIM的有效波阻抗与空气相匹配，同时具有接近零的指数，因此NZIM超材料具有将入射辐射波向法向准直的特性。利用CST微波对该天线进行了仿真和研制。明显地，天线增益和指向性分别提高了6.07和5.42。

A Metamaterial Antenna Based Near Zero Refractive Index(NZIM) Unit-Cell as a Superstrate For Directivity and Gain Enhancement

In this communication, we present an enhanced gain and directivity UWB elliptical metamaterial antenna based on the Near Zero refractive Index (NZIM). The operating frequency range is from 3.1GHz to 20GHz. The NZIM superstrate metamaterial has a property thats could collimates the incident radiated wave towards the normal direction because the effective permeability and permittivity of the (NZIM) are optimized to synchronously approach zero, this effects leads the NZIM to have an effective wave impedance matching with air and near-zero index simultaneously. The proposed antenna is simulated and developed using CST microwave. Obviously, the antenna gain and directivity are improved by 6.07 and 5.42 respectively.
