DESIGN AND SIMULATION OF PRINTED MICRO STRIP LOW PASS FILTER BASED ON THE ELECTROMAGNETIC MODELS 18GHZ PRINTED MICROSTRIP LOWPASS FILTER USING X-MODELS

Abstract

—this paper presents the Design, Simulation and characterization of Printed Micro strip Low Pass Filter based on 15 mil Alumina substrate. Simulations show a comparison between a pure EM simulation with EM Sight and a more efficient hybrid approach that combines EM analysis (using X-Models) with conventional circuit simulations and both approaches match the measured data. Furthermore, the proposed paper has four different low pass filter designs, lumped design; basic designs uses only micro strip lines; advanced design uses multiple edge coupled micro strip lines, EM sight design provides a very sharp cut-off frequency response with low insertion loss, results having great agreement with excellent correlation. Tuning and Optimization of the design is carried out using AWR Microwave office tool.
