A Novel DP-EBG Structure for Low-pass Filter of Wide Stopband
In this letter,a novel dual planar electromagnetic bandgap(DP-EBG)microstrip low-pass filter structure is investigated.The presented structure is realized by superposing two different one-dimensional(1-D)electromagnetic bandgap(EBG)structures which have different center frequency of the stopband into a coupled dual-plane configuration.Both simulation and experimental results have verified that only two cells of the proposed structure are enough for the measured-20 dB stopband from 3.7 GHz to 14 GHz with a excellent low-pass performance in a small circuit area.Since this novel design demonstrates superior low-pass filtering functionality,we expect this novel structure is widely used for wideband monolithic circuit applications.
