Abstract

A dual‐band bandpass filter using a new dual‐band dual‐behavior resonator (DBR) structure is proposed.The new dual‐band DBR consists of only two stopband elements connected in parallel. One is a uniform impedance open‐circuited stub and the other is a stepped impedance open‐circuited stub. The concept of stepped impedance resonator is utilized to realize the sencond band characteristics at desired frequencies. Experimental results in microstrip technology are presented, which validate our idea. © 2011 Wiley Periodicals, Inc.

## Abstract In this article, a second‐order dual‐band bandpass filter is designed. The filter consists of two dual‐band resonators connected by a dual‐band admittance inverter. The dual‐band resonator unit is made of two shunt stubs that coordinately produce two resonances. A novel dual‐band quarte

## Abstract This article presents a dual‐mode dual‐band bandpass filter based on double‐sided parallel‐strip line with an inserted conductor plane. Due to the isolation property of the conductor plane, this structure can provide two separate transmission paths to generate two passbands. No extra co
