Abstract

A novel compact and multiband dipole antenna with a planar fractal-inspired configuration is presented. Several series capacitances and a parasitic element are employed as loading. Results show that the loading improves the impedance matching and enables the proposed antenna to radiate at multiple frequency bands. In addition, the proposed loaded dipole antenna offers a high degree of miniaturization in comparing with the unloaded host dipole antenna. The simulated |S₁₁| response of the proposed loaded dipole antenna shows five distinct resonant bands with the center resonant frequencies of 1.52 GHz, 3.62 GHz, 4.6 GHz, 6.9 GHz, and 9.43 GHz. A fabricated prototype has compact dimensions of the 37 mm × 14 mm × 1.6 mm, and exhibits good agreement between the measured and simulated S-parameters.
