Abstract :
In this paper, new structures with nonlinear phase responses are proposed based on the composite right /left-handed (CRLH) transmission lines. Using such improved CRLH structure, arbitrary dual-band microstrip components have been realized, such as a quarter-wavelength open/short-circuited stub, and a dual-band branch-line coupler, etc. This has been demonstrated by both simulated and measured results. Compared to the conventional CRLH structures, the novel components are more compact and are easier to be realized.
