A family of multiband metamaterial-inspired dipole antennas are reported. These antennas are based on a dipole integrated in a planar configuration with capacitively loaded loops (CLLs) as their near-field resonant parasitic (NFRP) elements. In the realized structures, the number of operating frequencies is determined by the size of the CLLs and their proximity to the printed dipole. Simulation results explain the design features and demonstrate that the structures present a multiband behavior. Three corresponding prototypes were fabricated and tested. The measured impedance mismatch and radiation pattern results are presented and are shown to be in good agreement with their simulated values.
