A mobile wireless communications device includes a wireless transceiver, and a reconfigurable antenna coupled to the wireless transceiver. The reconfigurable antenna has a dielectric substrate, with a plurality of electrical conductors on the dielectric substrate laterally adjacent the ground plane and arranged in a series of spaced apart antenna loops with each successive outer antenna loop surrounding an adjacent inner loop, each antenna loop having a pair of endpoints. A plurality of switches are associated with respective endpoints of the antenna loops. A processor is adapted to reconfigure the reconfigurable antenna and couple the wireless transceiver thereto via the plurality of switches.
