Efficient Electrically Small Antenna Design Using an Electric Dipole in a Multi-layered ENG Metamaterial Shell

There continues to be a great desire for electrically small antennas that could be tailored to satisfy a wide range of specifications for a variety of applications including wireless communications, wireless networks, and sensor arrays. Unfortunately, the traditional electrically small antenna has a number of well-known drawbacks such as a large impedance mismatch with a power source and a poor radiation efficiency. If an efficient, electrically small antenna could be developed, it would have an immediate impact on these and other applications.
