Abstract
An antenna comprises a resonator and a waveguide. The resonator comprises at least one body having a negative effective electrical permittivity or a negative magnetic permeability when a resonance is excited therein by electromagnetic radiation lying in some portion of the microwave spectrum. A termination of the waveguide is situated adjacent the resonator. The resonator is conformed such that at the resonance, there is efficient coupling between the resonator and the waveguide.
