设计制作微带电路和微带天线需要知道微带的参量。我们提出的网络扰动法的原理类似于切割微带线法。但代替对微带线的切割,用金属或介质片沿微带线平行滑动,同样可测出微带波长.这种方法应用于有介质层测量也同样有效。分析表明,这种方法还可测出微带线的衰减,是一种有效的测量方法.
Designing microstrip circuits and microstrip antennas requires knowledge of the microstrip parameters. The principle of the network perturbation method we proposed is similar to the cutting microstrip line method. However, instead of cutting the microstrip line, a strip of metal or dielectric may be used to slide along the microstrip line in parallel to detect the microstrip wavelength. This method is also effective for measuring the dielectric layer. Analysis shows that this method can also measure the attenuation of microstrip line, which is an effective measurement method.
