JWCN_V5_N4_RP5 Pooja Gupta Ashutosh Kumar Journal On Wireless Communication Networks 2320 - 2351 5 4 27 31 Coupled Line, Microwave Filter, CST, ADS, GPS, X-band This paper presents the design of narrow band-pass filter and wide band-pass filter using microstrip coupled line structure. The narrow band-pass filter is designed to operate at dual center frequencies of 1.227 GHz and 1.575 GHz for GPS and the wide band-pass filter to operate at X-band segment (8-12 GHz) of microwave frequency spectrum with center frequency of 10 GHz. The device dimensions are calculated using MATLAB coding and the simulative analysis of the filter is done using ADS and microwave studio software. The filter response by CST and ADS are compared using MATLAB. January - March 2017 Copyright © 2017 i-manager publications.
