A mobile wireless communications device (10) includes a wireless transceiver (18), and a reconfigurable antenna (11) coupled to the wireless transceiver. The reconfigurable antenna has a dielectric substrate (22), with a plurality of electrical conductors on the dielectric substrate laterally adjacent a ground plane (16) and arranged in a series of spaced apart antenna loops (14a, 14b, 14c) with each successive outer antenna loop surrounding an adjacent inner loop, each antenna loop having a pair of endpoints (23a, 23b, 23c, 25a, 25b, 25c). A plurality of switches (22a, 22b, 22c, 24a, 24b, 24c) are associated with respective endpoints of the antenna loops. A processor (20) is adapted to reconfigure the reconfigurable antenna and couple the wireless transceiver thereto via the plurality of switches.The reconfigurability of the reconfigurable antenna (11) provides frequency, pattern, and polarization reconfigurability. |
