Abstract
A single-layer microstrip structure with variable line width is considered in order to create, by periodic repetition, an electromagnetic bandgap structure. The width of the line is varied in such a way as to guarantee a sinusoidally modulated value of the effective dielectric constant along the longitudinal direction. By repeating periodically the structure in the orthogonal direction, a high-impedance surface is obtained. Continuous and discrete line configurations are considered, and the performances of the two-dimensional structure with respect to the uniform line case are compared.
