A dual-band efficient metamaterial-inspired electrically-small magnetic-based antenna

This paper introduces a dual-band magnetic-based two-dimensional (2D) efficient metamaterial-inspired electrically-small antenna, i.e., a 2D dual-band magnetic-based EZ antenna. The combined 2D planar antenna system is naturally matched to the source at 900MHz and 1800MHz; and thus, it is an efficient radiator at these frequency bands. It will be shown that this antenna system acts as a resonant electrically-small magnetic dipole over a finite perfect electrically conducting (PEC) ground plane at these design frequencies. The performance of the reported antenna system was simulated with Ansoft´s High Frequency Structure Simulator (HFSS) and Ansoft´s Designer v3. The single-band 2D magnetic-based antenna integrated with a lumped element capacitor was fabricated, and the measured reflection coefficients were compared to the predicted numerical simulations. The dual-band two-dimensional magnetic-based EZ antenna radiation characteristics at the design frequencies are presented.
