  • Mobile communication device having multiple frequency band antenna
    Patent number: 6677903
    Abstract: A mobile communication device comprises an antenna and a housing enclosing a circuit board having communication components disposed thereon to transmit and receive communication signals. The antenna includes a substrate having opposite first and second surfaces, a planar conducting layer, a quarter wave choke strip, and a monopole conducting layer. The planar conducting layer is disposed on the first surface of the substrate, while the quarter wave choke strip and the monopole conducting layer are disposed on the second surface of the substrate. The quarter wave choke strip is electrically coupled to the planar conducting layer and connected to the monopole conducting layer. The antenna may be configured to work in three frequency bands: an upper band, a middle band, and a low band.
