A miniaturized artificial magneto-dielectric resonator antenna with split ring resonators
Naturally occurring high permeability materials are widely used in antenna miniaturization at VHF-UHF frequency range. However, they are unable to be used at frequencies beyond 500 MHz due to their high loss. The main idea of this paper is to reproduce the magnetic behavior using metallic inclusions for low-loss microwave applications. In this paper, an artificial magneto-dielectric resonator antenna (AMDRA), operating at 3.857 GHz, based on split ring resonator (SRR) is presented. The simulation results are compared to those of the conventional dielectric resonator antenna (DRA) with high permittivity. It is shown that the size of the proposed antenna is 1.8 times smaller than that of the conventional DRA, with an efficiency of 88% and a gain of 5.8 dBi. This demonstrates that the artificially induced permeability can be effectively used in dielectric antenna miniaturization.
