Dual-frequency printed dipole loaded with metamaterial particles

Abstract

In this paper a dual-frequency printed dipole is presented. This antenna is made by loading a dipole printed on both sides of a FR-4 substrate with metamaterial resonant particles. First, a simplified model based on a printed dipole loaded with LC parallel resonators is used as an approximation. This model shows the dual-band performance of the antenna. Then, an implementation of the antenna is developed by loading the printed dipole with metamaterial particles, in particular split ring resonators (SRRs). Both resonant frequencies can be arbitrarily chosen and they depend on the self-resonant frequencies of the dipole and the SRRs. In this paper we propose a dipole working at 1.32 GHz and 2.08 GHz simultaneously (1.58 ratio).
