Abstract
Based on the excellent microwave characteristics of flexible liquid crystal polymer substrate,this paper designs and implements a miniaturized triple-band bandpass filter.Through the adoption of three-dimensional layout in multilayer LCP substrate and innovative use of vertical spiral inductors and vertical interdigital capacitor structures,the miniaturization of the filter is achieved.The research focuses on analyzing key technologies of multilayer spiral inductor design and vertical interdigital capacitor design,with an in-depth discussion on the effects of defected ground structures.Test results show that the filter features small size and excellent performance,with high consistency between measurement and simulation results,providing a new technical solution for the development of miniaturized communication systems.
