A simple T-shaped monopole is converted into a metamaterial antenna by loading lumped capacitors and inductors on the metal wire. The new metamaterial antenna could sustain a half-wave resonance even when its length exceeds several free-space wavelengths. An 80mm-long monopole initially resonating at 1.3GHz is modified to operate at 3.6GHz with a reduced 3dB H-plane beamwidth of 48°.
