Abstract

A new type of microwave dual-passband planar filter exploiting signal-interference techniques is presented. The described filter approach consists of transversal filtering sections shaped by two transmission lines connected in parallel. This transversal section, operating under feedforward signal-combination principles, allows dual-band bandpass filtering responses with several transmission zeros to be synthesized. A set of analytical formulas and guidelines for the design of the dual-passband transversal filtering section are provided. Moreover, its practical usefulness is verified through the development and testing of a microstrip prototype for the 1.4/2.6-GHz dual band.
