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.
