微带及渐变微带中瞬态信号传输特性的小波变换分析

A Study of Propagation of Transient Signals in Microstrip and Taper Microstrip Transmission Lines Using Wavelet Transformations

本文利用小波变换对瞬态信号在微带及渐变微带线中的传输特性进行了分析，与传统的傅立叶变换分析相比，小波分析具有速度快、能够分析局部传输特性的优点。文中给出了高斯信号和矩形脉冲信号在微带中及矩形脉冲信号在渐变微带中的传输波形，所得结果对研究超高速与超宽带瞬态信号的传输及电路设计有一定的参考价值。

In this paper,we study the propagation property of the transient signals on the microstrip and taper microstrip liner using the method of the wavelet transform. This method has the advantages of fast compulating and localizing the wave form at any time and at any point along the transmission line to zoom compared with the the conventional Fourier transform. We give the dispersion of the Gaussian signal and the rectangle pulse signals on the microstrip and the taper microstrip lines. The results can serve as referance in the study of the propagation of the ultrahighspeed and ultrawideband transient signals and in the design of MIC and MMIC.
