| 摘 要： | 本文基于环形几何上的超二次曲线表示，分析一组印刷环天线的谐振特性，首先给出求解天线电流分布和辐射场的统一数值计算公式，然后通过改变超二次曲线的开头参数，分析印刷在不同介质基片上环形天线的形状与其谐振电阻和谐振环周长的关系。结果表明，可以通过调整环形天线的几何形状获得与馈线相匹配的谐振电阻。

| Abstract: | The resonance characteristics of a set of pri nt ed loop antennas are analyzed by means of a superquadric representation for clos ed curves. A unified numerical formulation is presented for solving the current distribution and radiation fields. The dependence of the resonant resistance and resonant loop perimeters on the superquadric parameters is investigated for the loop antennas printed on various dielectric substrates. It is shown that one ma y obtain a perfect match to the feed by controlling the geometry of the printed loop antennas. |
