摘要

对两种火山烟雾贴片天线进行了比较,一种是CPW馈电,另一种是微带馈电。这两种天线都是从圆形贴片结构演变而来的,通过软化边缘来获得天线参数的改进,这与John Kraus提出的理论一致。经过改进,反射系数和谐振频率的数量在整个工作带宽中有所改善。工作频率范围为500mhz ~ 15ghz,设计最佳工作频率为4.5 GHz左右。天线馈电阻抗建议为50欧姆。通过构造出仿真响应最佳的天线来测试实验的实际性能。

Comparison between quasi circular planar antennas with microstrip and CPW feeding
We present comparison between two volcano smoke patch antennas, one of them with CPW feeding and the other with microstrip feeding. Both antennas are an evolution from a circular patch structure softening the edges to obtain improvements in the antenna parameters, agreeing with the theory proposed by John Kraus. After evolution there were improvements in reflection coefficient and number of resonant frequencies throughout the operating bandwidth. The operational frequency range is from 500 MHz to 15 GHz while the best operational frequency (by design) is about 4.5 GHz. The antenna feeding impedance is proposed to be 50 ohms. There were constructed antennas with the best simulation response to test the practical performance of experiment.
