摘要
给出了一种分析平板和平板锥角喇叭天线辐射特性的新方法。这种方法把天线辐射问题转换为波导不连续性结构的传输问题,从而避免了传统天线分析方法中求解场源问题的困难,大大简化了分析过程。同时,采用将模匹配和多模微波网络理论相结合的方法来计算相关波导不连续性的传输问题,使计算结果有较高的精度。通过计算值与理论值的比较,证实了本文方法的有效性和精确性。
A new approach is presented to analyze the parallel-plate and tapered horn antennas, in which the radiation problem is transformed to solve the related discontinuity problem in waveguides, so that the difficulty caused by field-source problem of the traditional antenna analysis is avoided and the analysis procedure is tremendously simplified. Meanwhile, the method that combines the mode-matching approach with the muhimede microwave network theory is used to solve the discontinuity problem obtained in the modeling for getting higher accuracy resuhs. The validity and accuracy of the present approach are verified by the comparison between the computed and the theoretical results.
