摘　　要：基于矩量法数值方法,研究了由梯形弯折线构成的单极子天线的谐振特性。着重于分析在天线高度和宽度都有明确尺寸要求条件下,天线输入参数与梯形弯折线弯折次数的关系以及与弯折角的关系。结果表明,弯折角的改变对天线谐振特性具有很强的调节作用,恰当地选择弯折角可以有效地改变天线的谐振频率与带宽,提高天线的辐射能力和匹配性能。A compact trapezoid meander line monopole antenna is presented. The design analysis of the antenna is performed with the method of moments. The reliability of the numerical analysis is demonstrated by the experement result in special case. A detailed investigation is focused on the comparative analysis of the input parameters for different configuration of the antenna. It is demonstrated that changing the indentation angle of the trapezoid meander line is a simple but rather effective tuning method to lower resonant frequency and improve the performance of radiation and match for the antennas.
