Transmission-line metamaterials based on complementary split-ring resonators (CSRRs) are shown to support forward, backward, electroinductive, and complex waves. Two CSRR-based lines are considered: 1) stopband microstrip lines simply loaded with CSRRs, and 2) passband microstrip lines loaded with CSRRs and series gaps. The effects of interresonator coupling on bandwidth enhancement are analyzed on...
Equilateral triangular complementary split ring resonators which is substituted for the Koch-fractal curves is used to the composite right/left-handed transmission lines, and the resonant frequency is reduced by 22% and 34% respectively when 1 and 2 order Koch-fractal curves complementary split ring resonators are applied. The equivalent circuit model of the structure is presented and the electrical...
This paper presents a new uniplanar hexagon EBG structure for circuit size reduction applications. The EBG is placed at the ground plane of the microstrip line to increase the distributed capacitances and inductances for slowing the wave propagation. The simulations are performed by the commercial software using finite-element-method (FEM) to check the insertion loss and the slow wave behavior for...
