Abstract
A multiband antenna includes one or more first antennas embedded within a second antenna. The one or more first antennas can include a folded dipole, and the second antenna can include a monopole. The folded dipole and the monopole may operate at different resonant frequencies. Because the folded dipole is embedded in the monopole, rather than being a separate antenna, near-field coupling between the antennas may be reduced, resulting in enhanced radiation patterns by one or both antennas. More complex antenna structures can also be constructed having multiple antennas embedded within one or more antennas.
