Antenna assembly (100) to be worn by a user includes a low-band dipole antenna (310) and at least one high band dipole antenna (312). The high-band dipole antenna is comprised of a high-band dipole feed (102) interposed at a location along a length of a low-band dipole element (105,110). The high-band dipole feed divides the first low-band dipole element into a first high-band dipole element (128) and a second high-band dipole element (130). One of the high-band dipole elements (130) is formed as a flexible electrically conductive sleeve. An RF control device (308) is provided for selectively directing RF energy in a high-band to the high-band dipole feed (102), and for selectively directing RF energy in a low-band to the low-band dipole feed (202). |
