Abstract
An antenna system is installed on a wireless device which is designed to be placed near the ear of a human user. The antenna system has a first antenna configured to transmit and receive signals. The first antenna is located at the end of a boom. The boom rotates so as to displace the first antenna away from the user's head when wireless device is in use in close proximity to the user's head. In one embodiment, the system includes a monopole whip antenna and a switching mechanism to alternatively activate the monopole whip antenna and the first antenna.
