| Abstract: |
| A novel tri-band filter composed of stub loaded resonator (SLR) and de
fected ground structure (DGS) resonator is presented in this paper. The SLR with
interdigital coupling forms two passbands centered at 2.45 GHz and 5.25 G
Hz, and the DGS resonator on the back forms a bandpass response at 3.5 GHz
, which have realized independent passband design. Based on this method, a tri-
band filter operating at 2.45/3.5/5.25 GHz is designed, fabricated and chara
cterized, which can be used in wireless communication. The simulated and measure
d results show good agreements and validate the proposed design method. |
