Parametric Analysis on the Effect of Open Circuit Stub Resonator Towards the Performance of Ultra-Wideband Stepped Impedance Low Pass Filter

摘要

c and also transmission zeroes frequency, f_z in order to be used for different applications. Thus, the combinationof SILPF and OCSR and also rectangular patch combined feed-line structure exhibits wide rejection bandwidth better than ?20 dB from 8.20 GHz up to 23.38 GHz. The filter design is simulated on Roger 4003 with relative dielectric constant, ?_r of 3.38 and also thesubstrate thickness, h of 0.508. This proposed simulated filter design has shown promising result and could be further analyzed for experimental works and fabrication. Therefore, the filter is beneficial for communication and radar systems particularly to avoid the interference andharmonic as well as the spurious response signals.]]>
