چکیده

Abstrac


t Defected coplanar waveguide (CPW) resonator has been analyzed, and multi-band bandpass filters with individually controllable passband have been developed. New dual-band and tri-band bandpass filters which center at 2.4/3.5/5.2 GHz have been designed, fabricated and measured. The measurements demonstrate the new presentations. The measured filter passband insertion losses are less than 2.7 dB. It has been noticed that the filter center frequencies can be individually controlled, and the bandwidths can be individually adjusted. Advantages of the new design are not only its simple and compact circuit topology, miniature circuit size, but also its less electromagnetic leakage.

نتیجه گیری

5. Conclusion


New CPW multi-band bandpass filters with controllable pass- bands have been developed. For arbitrary passband, the new design has high rejection level at upper stopband. The proposed CPW bandpass filters have simple and compact structures, minia- ture circuit sizes, controllable center frequencies and bandwidths, and less electromagnetic waves leakiness. The proposed dual-band and tri-band BPFs are fabricated and measured, the experimental results verify the predictions. The proposed CPW filter design scheme is also can be sued for multi-band bandstop filter design.
