Abstract:
1. An antenna coupling apparatus comprising: a first antenna connected to a portable radio terminal, said first antenna being elongated in an axial direction; a second antenna separated from said first antenna; an electromagnetic coupling element consisting of a conductor that electromagnetically couples said first and said second antennas together arranged adjacent to said first antenna at a first location along the axial direction of said first antenna; a ground conductor element arranged proximate said first antenna; and a reflective ground element separate from said electromagnetic coupling element arranged adjacent to said first antenna and electrically connected to the ground conductor element, wherein said reflective ground element is physically in parallel with and a predetermined distance from said electromagnetic coupling element along said first antenna in the axial direction for reflecting power transmitted from or received by said first antenna toward said electromagnetic coupling element.
