摘　　要：结合已有文献中提出的线面结合处理方法,对各种连接基函数进行了综合分析,提出一种新颖的线面连接处连接基函数.该连接基函数不存在函数自身奇异性问题,且形式简单、精度高,可以应用于任何线面相连的情形.采用矩量法分别计算了线天线位于导体表面、边缘以及顶点三种情况的输入阻抗,数值结果表明了所提连接基函数的准确性和有效性.The multiform junction basis functions are analyzed comprehensively based on the method of dealing with junction between wire antennas and conductors presented in the literatures. A novel junction basis function is proposed, which does not exit the problem about function self singularity. The function can be used in such cases as arbi- trary connections between wire antennas and conductors due to its simple form and high precision. The input impedances of three cases including wire antenna positions at the conductor surface, edge and vertex are calculated based on the method of moments （MoM）, respectively. The numerical results calculated show the validity and effective- ness of the junction basis function.
