Continuously Tunable Dual-mode Bandstop Filter
Amir Ebrahimi, Thomas Baum, James Scott +1
A varactor-based tunable bandstop filter has been proposed in this article. The proposed filter is based on a dualmode circuit developed by introducing inductive and capacitive cou…
Narrowband Bandpass Frequency Selective Surface with Miniaturized Elements
Amir Ebrahimi, Thomas Baum, James Scott +1
This article presents a bandpass frequency selective surface (FSS) with a narrowband frequency response. The designed FSS is made of miniaturized elements unit cell. The operation…
Differential Bandpass Filters Based on Dumbbell-Shaped Defected Ground Resonators
Amir Ebrahimi. Thomas Baum, Kamran Ghorbani
This letter presents a dumbbell-shaped defected ground resonator and its application in the design of differential filters. The operation principle of the dumbbell-shaped resonator…
