Abstract
A communication device operable in multiple frequency bands includes a branching antenna adapted to operate in at least two frequency bands. The antenna includes a first conductive element having a connection at one end for driving the antenna. The first conductive element is resonant at a first frequency. On the first conductive element, a feed point is located away from either end of the first conductive element, and particularly the driving connection point. A second conductive element is coupled to the feed point such that the second conductive element in conjunction with the portion of the first conductive element between the drive connection and the feed point is resonant at a second frequency. This allows for a more compact and versatile multi-band antenna.
