Abstract :
We present electrically small multiband planar antennas for wireless applications, enhanced by negative permeability metamaterial rings. The presence of the rings results in a significant reduction of the operation frequency. Two different feeding methods (microstrip and coplanar) are considered, resulting in efficient, entirely planar structures.
