Coupling coefficients of combline resonators [PDF]

open access: yesSBMO/IEEE MTT-S International Conference on Microwave and Optoelectronics, 2005., 2006
Bandpass filters require elements that behave as series or parallel resonant circuits. In this paper, we discuss a variety of couplings between combline resonators in bandpass filter applications. Coupling coefficient used in filter realizations has been precisely calculated.
