The design and modeling of an embedded-circuit metamaterial with epsi-mu constitutive parameters as the substrate for patch antennas with potential advantage of magneto-dielectric metasubstrate for the design of small antennas having relatively wide bandwidth is presented.Abstract:
The design and modeling of an embedded-circuit metamaterial with epsi-mu constitutive parameters as the substrate for patch antennas is presented. The magneto-dielectric metasubstrate is constructed of periodic resonant loop circuits embedded in a low dielectric host medium, and is capable of providing both permittivity and permeability material parameters at any frequency of interest. The embedded-circuit building blocks are very small in size (<lambda/20) and constitute artificial material molecules. Geometric control of the embedded-circuits allows epsiv and mu to be tailored to the application. A transmission line circuit model analogy is developed to theoretically investigate the behavior of designed embedded-circuit metamaterial and predict its physical parameters. In addition, a full wave analysis based on finite difference time domain (FDTD) technique is applied to comprehensively characterize the complex periodic structure. The potential advantage of magneto-dielectric metasubstrate for the design of small antennas having relatively wide bandwidth is investigatedread more
