Abstract
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.
