Abstract:
1. Mobile communication apparatus, comprising: a housing including communication circuitry and a printed wired board (PWB) formed with a signal terminal for an antenna, and an electrically-conductive ground for said communication circuitry; an antenna carried by said housing and electrically connected to said signal terminal of the communication circuitry in the PWB, said antenna being designed to operate in at least one radio frequency band; and an electrically-conductive ground-enlarger carried by said PWB and electrically connected to said electrically-conductive ground of the PWB such that said electrically-conductive ground-enlarger effectively enlarges said ground of the PWB to load the antenna in said radio frequency band, and thereby to enhance the operating efficiency of the antenna particularly in the lower part of said radio frequency band, and to widen said radio frequency band.
