Özet

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 approximate to 1.6-2.0 dB), and have high (80%) radiation efficiencies at all of their operating frequencies.
