Abstract

The design and performance characteristics of metamaterial-inspired electrically small, single, dual and triple band antennas at the GSM (1.93-1.99 GHz), ISM (2.43-2.4835 GHz), and WiMAX (3.3-3.6 GHz) frequencies are reported. These antennas are based on a coaxially fed printed dipole integrated in a planar configuration with capacitively loaded loops (CLLs) as its near-field resonant parasitic radiators. In the proposed topology, the number of operating frequencies is determined by the number of CLLs. These antennas are geometrically simple, operate as magnetic dipoles (directivities ∼1.6-2.0 dB), and have high (≥80%) radiation efficiencies at all of their operating frequencies.
