小波在DGPS微带接收天线分析中的应用

The application of wavelet to the analysis of DGPS microstrip receiving antenna

为了解决 DGPS双贴片积叠式微带天线设计盲目性大、成功率低的问题 ,采用谱域矩量法对这种天线进行了分析 ,并将小波基用于分析中 ,使计算速度大大提高 .由双贴片积叠式微带天线的双调谐等效电路 ,采用传输线法导出了天线输入阻抗的计算公式 。

In order to solve the problem of big blindness and little success in the design of double patches stacked microstrip antenna used in DGPS system, by using moment method in the spectral domain this paper analyzes this kind of antenna which makes the computing velocity increase obviously. It deduces a compute formula of input impedance of this kind of antenna by transmission line methed through the double harmonic equivalent circuit of double patches stacked microstrip antenna. This formula has a theoretical significance for the design of this kind of antenna.
