Millimeter-Wave Meta Cells Loaded Coplanar Transmission Line for Component Applications

In this work, a planar transmission line loaded with square shaped split ring resonator (SRR) metamaterials works around 150 GHz is modeled and validated by means of full-wave electromagnetic simulations. The transmission characteristics of such a transmission line is reported. The SRR loaded coplanar waveguide (CPW) structure exhibits stop band characteristics in response to the resonance of the inductively coupled SRR rings excited by the magnetic fluxes through the rings. A parametric analysis of the rings and arrays of SRRs carried out to predict the behavior of the meta cells loaded transmission line. Since these metamaterials are much smaller than the feeding signal wavelength, these metamaterials loaded transmission lines are potentially useful to optimize size and quality factor of millimeter-wave circuit components and radiating elements
