摘要: Tri-band bandpass filter using centrally loaded resonators is presented in this article. The triple-passband characteristics are realized by properly controlling the lengths and impedances of uniform impedance resonator stub. To illustrate concept, two tri-band filters designed, fabricated, measured. Simulated measured results found to be good agreement with each other. prototype achieve insertion loss 1.6, 1.9, 1.9 dB at 2.4, 3.5, 5.8 GHz, 1.2, 1.3, 1.3 1.57, 2.45, 5.2 respectively. © 2013 Wiley Periodicals, Inc.
