There is disclosed a reconfigurable antenna device comprising a substrate having first and second opposed ends and first and second opposed side edges, the substrate incorporating a main groundplane. The antenna device further comprises a dipole antenna having first and second arms each having a proximal portion and a distal portion, the proximal portions extending substantially adjacent and parallel to the first end of the substrate and the distal portions respectively extending substantially adjacent and parallel to the first and second side edges of the substrate. Distal ends of the first and second arms are connected to the main groundplane or otherwise grounded. Additionally, there is provided a main chassis antenna having first and second arms extending substantially adjacent and parallel to the first end of the substrate. The main chassis antenna is configured for excitation by RF currents in the main groundplane. Finally, there are provided first and second auxiliary chassis antennas, the first auxiliary chassis antenna being disposed at the first end of the substrate substantially adjacent to the proximal portion of first arm of the dipole antenna and the first arm of the main chassis antenna, and the second auxiliary chassis antenna being disposed at the first end of the substrate substantially adjacent to the proximal portion of the second arm of the dipole antenna and the second arm of the main chassis antenna. The first and second auxiliary chassis antennas are configured for excitation by RF currents in the main groundplane.
