摘要
提出了一类新型表面波天线,并分析其辐射特性。研究结合预修正快速傅里叶变换方法和矩量法的算法求解体面结合积分方程,快速准确分析金属介质混合问题。通过对比表面波天线的辐射方向图和驻波测试曲线,验证了算法的准确性。分析了该表面波天线的金属电流分布,说明该天线具有单振子天线的辐射特性,为天线高增益、小型化设计提供了思路。
A novel type of surface-wave antenna(SWA) is introduced in the paper,and identities of its radiation are analyzed.Method of moment(MoM) is combined with precorrected-FFT(p-FFT) method to solve the composite volume and surface integral equations(VSIE),and to analyze composite metallic\dielectric electromagnetic problems.By comparing the calculated results with that of radiation patterns and return loss,the Schauber-wilton-Glisson(SWG) has similar radiation characteristics with a monopole.It provides a new idea to design a high-gain,small-size antenna.
