A Method of Designing in Microstrip Equalizer Based on the Substructure Method

ABSTRACT

To make the optimization design result of system and components which, contain ordinary non-uniform substructures, meet the measurement criteria better. According to the microstrip equalizer’s complex electromagnetic characteristics, the Substructure Analyzing Method of Interconnect-net based on parameters matrices measurement database is proposed and verified which combines the measure technology with database. The analysis and engineering design of the abnormal-edge microwave apparatus is realized. The method treats the complex microwave structure as a interconnect of some simpler substructure, uses the measurement database to character the substructure whose electricity and magnetism property is difficult to exactly resolve and uses the net cascading method to get the overall net parameters. The method is the basis of a number of current and pending patents. It may also lead to other fields such as the design of shortwave multimode multifeed antenna system. In this paper, a typical example of microstrip equalizer optimization is given to illustrate the efficiency of the method.
