Moore Curve Fractal‐Shaped Miniaturized Complementary Spiral Resonator

In this article, a novel design of complementary spiral resonators as miniaturized metamaterial particles based on Moore curve fractal shape is presented. The proposed design of metamaterial unit cell is investigated using a microstrip line loaded with series gap discontinuities and implementing fractal shape complementary spiral resonator in ground plane that behaves as a composite right left hand transmission line. It is observed that Moore curve fractal-shaped spiral resonator provides 49% size reduction as compared to conventional split ring resonators. An equivalent lumped element circuit model of the proposed composite right left handed transmission line is developed to analyze the proposed topology. A close agreement between electromagnetic simulation, circuit simulation, and measurement is obtained. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1950–1954, 2013
