A dual-passband microstrip open-loop resonator filter

In this paper, a design technique that includes a synthesis procedure and a realization method for a microstrip open‐loop resonator filter with two passbands is described. Transmission zeros of the filter‐transfer function are employed to split a single passband into two passbands, and the filter‐co...

Zusammenfassung:In this paper, a design technique that includes a synthesis procedure and a realization method for a microstrip open‐loop resonator filter with two passbands is described. Transmission zeros of the filter‐transfer function are employed to split a single passband into two passbands, and the filter‐coupling structure used to realize two passbands is also given. The measured result shows good agreement with the synthesized one. © 2005 Wiley Periodicals, Inc.
