救急):拜托帮忙翻译这段摘要

This paper first briefly introduced the classification of filter, the development trend of development, and now. Theoretically the detailed introduction of microwave filters the design theory and method, which mainly introduced into means about the type of bandpass filter the basic theory and method of design. Then, by means of short circuit terminal type filter into the design principle and method, using Matlab software programming calculated the geometric dimension bandpass filter, and then the initial value of the filter with ADS, and modeling of initial geometric parameters of the simulation, optimization, and eventually reached as far as possible the original design of data, and ADS for filter and its simulation, the formation of the layout of the object finally.
