摘要

讨论了三频带短段加载u型槽或矩形槽型切割rmsa。该短段降低了贴片的TM02模式的共振频率，并与TM10模式一起产生双波段响应。在此基础上，分析了狭缝对短段加载矩形微带天线三波段响应的影响。研究了表面电流分布和辐射方向图。u型槽或矩形槽降低了贴片下一个高阶TM12模式的谐振频率，并与改进的TM10和TM02模式一起产生三波段响应。通过对表面电流分布的研究，提出了修正TM10、TM02和TM12模式下的谐振长度公式。使用所提出的公式计算的频率与模拟结果非常吻合，在整个时隙长度范围内，误差小于5%。

Formulation of Resonant Length for Triple Band Rectangular Microstrip Antennas

The triple band stub loaded U-slot or rectangular slot cut RMSAs are discussed. The stub reduces the resonance frequency of TM02 mode of the patch and along with TM10 mode yields dual band response. Further, an analysis to study the effect of slot on the triple band response in stub loaded rectangular micro strip antenna is presented. The surface current distributions and radiation pattern plots were studied. The U-slot or rectangular slot reduces the resonance frequency of next higher order TM12 mode of the patch and along with the modified TM10 and TM02 modes yields triple band response. By studying the surface current distributions, a formulation in resonant length at modified TM10, TM02 and TM12 modes is proposed. The frequencies calculated using the proposed formulations agrees closely with simulated results with % error less than 5% over the complete slot length range.
