Abstract: An antenna assembly for a mobile communication device includes two antennas. The two antennas are disposed in a cavity defined in a side frame member of the mobile communication device. The two antennas are disposed adjacent with a gap in between. An antenna feed point is disposed in connection with each antenna. One antenna element of each antenna is disposed on a surface of side frame member surrounding the cavity.

Abstract: An antenna apparatus includes a feeding antenna inside an electronic device and one or more antenna elements, such as a floating metal antenna, disposed on a rear cover of the electronic device. The floating metal antenna and a feeding antenna inside the electronic device may form a coupling antenna structure. The feeding antenna may be an antenna fastened on an antenna support (which may be referred to as a support antenna). The feeding antenna may alternatively be a slot antenna formed by slitting on a metal middle frame of the electronic device. The antenna apparatus may be implemented in limited design space, thereby effectively saving antenna design space inside the electronic device. The antenna apparatus may generate excitation of a plurality of resonance modes, so that antenna bandwidth and radiation characteristics can be improved.

Abstract: A cavity-backed slot antenna for an electronic device comprises a first conductive structure and a second conductive structure. A dielectric slot extends between the first conductive structure and the second conductive structure. A third conductive structure extends from the first conductive structure and is juxtaposed with the dielectric slot. A dielectric volume is partially enclosed by the first conductive structure, the second conductive structure, and the third conductive structure, and the dielectric volume comprises the dielectric slot.

Abstract: An antenna system for a mobile device includes a first electrically conductive member having a plurality of segments including at least a first corner segment and a central segment that is disposed adjacent to the first corner segment. A dielectric material is disposed in a gap between the first corner segment and the central segment. A second electrically conductive member is disposed within the mobile device. A first end of the second electrically conductive member is connected to the first corner segment. A portion of the second electrically conductive member away from the first end is electrically connected to a first feeding portion. The central segment is connected to a second feeding portion.
