Abstract： |
The present invention belongs to the field of microwave narrow-band filter technology and is microstrip line resonator and its microwave filter. The resonator has two annuluses with connected ends to constitute one single folding annulus structure, one of the annuluses includes one notch and the two annuluses have their connected ends as closed ends and the other ends as open-mouthed ends. The resonator may have three annuluses with successively connected ends to constitute one double folding annulus structure, the first annulus includes one notch and the first annulus and the second annulus have their connected ends as closed ends and the other ends as open-mouthed ends. The present invention also includes filter based on the microstrip line resonator structure, and the filter includes parallelly arranged single folding annulus resonators and double folding annulus resonators to constitute resonator array. The present invention has the advantages of small insertion loss, great extra-band suppression, etc. |
