There is disclosed an antenna device comprising at least first and second electrically conductive tracks disposed in at least first and second planes in a laminate dielectric structure. Each electrically conductive track has at least two electrical connection points on an external surface of the laminate dielectric structure. The antenna device is reconfigurable between a plurality of different antenna types by connecting the electrical connection points to external circuitry in different configurations. In this way, a single antenna device may be configured as two or more of: a dielectric antenna, a planar inverted-F antenna (PIFA), a planar inverted-L antenna (PILA), a loop antenna, a monopole antenna and a capacitively-fed antenna.
