Abstract:
Based on the Composite Right/Left-Handed (CRLH) Transmission Line (TL) approach this paper presents a 3-band T-Junction power divider. The proposed design strategy uses a stub-loaded TL for the right-handed portion of the line; this way, with respect to a conventional CRLH line, one more degree of freedom is available. Experimental and numerical results referring to a prototype using surface-mount capacitors and inductors are reported and discussed. It is demonstrated that the artificial transmission line (ATL) here presented is an optimum candidate for designing high-added value microwave devices. Furthermore, based on the use of metal-insulator-metal capacitors and short circuited stubs, a monolithic implementation is also proposed.
