Abstract

The novel technique of generalizing complex-to-complex impedance transformers (CCITs) with miniaturization is introduced in this paper. The generalized CCITs are designed based on conjugately characteristic-impedance transmission lines (CCITLs) along with the Meta-Smith charts (MSCs), resulting in convenient design equations. For illustration, a prototype of generalized CCITs is designed, simulated, and implemented with an asymmetric compact microstrip resonant cell (ACMRC), which is one of the CCITLs. The measurement results confirm that the proposed technique offers approximately 28.5% shorter in physical length compared to the CCIT designed using standard transmission lines.
