A composite right/left-handed (CRLH) series mode zeroth order resonator antenna (ZORA) and a CRLH half-wavelength antenna (HWA) with tunable directivity are presented and demonstrated to exhibit substantially higher directivity than a conventional patch antenna in the case of a 2.4 GHz (WLAN) design. Due to the special dispersion relation of a CRLH transmission line (TL), the length of CRLH TL resonators...
This paper investigates the influence of the grid density, i.e. the amount of nonnegligible wavelet coefficients (Haar) used to represent the electromagnetic field, on integral parameters, like scattering parameters. A band-stop filter based on an unbalanced composite right/left-handed transmission line (CRLH-TL) is the specific example evaluated. The TL-based metamaterial (MTM) has been simulated...
