Design and performance analysis of 1GHz edge coupled microstrip bandpass filter

摘要

This paper discusses an edge coupled microstrip filter centered at 1 GHz having 200 MHz bandwidth. The dielectric material used for the fabrication of the filter is FR4.It is having dielectric constant ε of 4.4.The CST software is used for simulation of designed microstrip bandpass filter. The insertion loss acquired is above -2dB and return loss acquired is below 15 dB. The results which is received are very useful for the L band.
