摘要

提出了一种具有改进增益和指向性的小型超宽带单极天线，用于微波成像。在贴片天线边缘引入阶梯阶，提高了天线的增益和带宽。在接地面处有缺陷的接地结构抑制了表面波电流，使得在1.6GHz -10.2GHz工作频率范围内，对-10dB反射具有更好的阻抗匹配。该贴片的增益和指向性分别提高了5 dB和6.35 dB。

A Compact Stair Case Monopole UWB Antenna for Radar Applications

A compact Ultra Wideband monopole antenna with improved gain and directivity is presented for microwave imaging applications. Introducing the staircase steps at the edges of the patch antenna improves the gain, bandwidth of the proposed antenna. Defective ground structures at the ground plane suppress the surface wave currents and result in a better impedance matching over the operating frequency of 1.6GHz –10.2GHz for -10dB reflections. The proposed patch results in an improved gain and directivity of 5 dB and 6.35 dB respectively.
