摘要：

Bandpass filters based on microstrip coupled ring resonators including spur-line filters to suppress higher harmonics have been investigated. Two topologies based on placing spur-line filters into or out of the coupled rings have been considered and compared. A harmonic suppression ratio > 30dB in a flat bandpass filter centred at 2.44GHz is obtained placing spur-line filters into and out of the microstrip coupled rings.
