In this talk, an equivalent circuit method has been proposed to understanding the physical mechanism of a windmill structure metamaterial (WSM). As we known, studying the physical mechanism mean to need to derived the expressions of permeability and permittivity. Noticed from some literature [1–3], they can't offer the researchers the principles of selecting the structural parameters for the desired...
A negative permittivity (ENG) zeroth-order resonance (ZOR) antenna with compact size and low profile is introduced in this paper. By adding a shorting via and applying capacitive coupling feeding technology, the antenna could operate in the center of f0 =5.084GHz, which is corresponding to the electric size 0.273λ0×0.273λ0×0.0136λ0 (where λ0 is the wavelength corresponding to the operational frequency...
