内场结构研究表明 ,方形微带天线含对角线的两个空腔横截面分别属于理想电壁和理想磁壁 .提出了两种新型三角形微带天线 ,在谐振频率不变的情况下 ,将天线贴片面积缩减了一半 .给出了用于分析三角形微带天线的一种新方法 ,理论计算和基于矩量法解的Ensemble软件模拟结果一致性很好 .
The study of the infield structure shows that the cross section of two cavities with square diagonal microstrip antennas belong to the ideal electric wall and the ideal magnetic wall, respectively. Two new triangular microstrip antennas are proposed. Under the same resonant frequency, Antenna patch area reduced by half.A new method for analyzing triangular microstrip antenna is given.It is in good agreement with the Ensemble software simulation results based on the method of moment and the theoretical calculation.
