ABSTRACT:
An apparatus is disclosed for a multiband antenna (102) in a communication device (100). An apparatus that incorporates teachings of the present invention may include, for example, an antenna having a finite ground surface (201, 401), and an elongated conductor (206, 406) that is characterized by a length and is spaced from the finite ground surface. The elongated conductor has a first slot (208, 408) extending through a substantial portion of the length of the elongated conductor, and a second slot (210, 410) having a shorter length than the first slot. The antenna further has a grounding conductor (216, 416) coupling the finite ground surface to the elongated conductor, and a signal feed conductor (214, 414) coupling to the elongated conductor.
