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...
