| 摘 要： | 利用腔模理论对一端封闭的小型化微带天线进行了理论分析,同时结合大量仿真实验数据分析,对传统矩形微带天线尺寸的计算公式进行了修正,并通过仿真结果对修正后公式的合理性进行了说明。在小型化的同时,为了提高天线的带宽,设计了一种折叠双层结构的天线。用HFSS10.0进行仿真后的结果表明,在1.15~1.21 GHz和2.52~2.62 GHz这2个频段上的相对带宽分别达到5.2%和4.1%,并获得了较高的增益和良好的辐射一致性。实现了小型化天线的宽带及双频特性。

| Abstract: | This paper analyzes a type of one port sealed compact microstrip antenna by cavity model theory.Combined with the results of large number of simulation,the traditional calculating formulas of rectangular microstrip antenna were corrected.Then,the rationality of the theoretical analysis and the formulas were underlined by the results of simulation of a single layer folding-shaped antenna.Increasing the bandwidth of the antenna on the basis of miniaturization,a dual-frequency antenna with sandwich folding-sha... |
