Abstract: An antenna assembly, an apparatus having the antenna assembly, and a method of manufacturing the antenna assembly are disclosed. Antenna performance in, e.g., mobile devices is improved via an antenna assembly which allows wide-angle beam scanning across a wide frequency bandwidth. Wide beam coverage may in turn contribute to improving multi-surface spherical beam coverage, such as in broadside direction and endfire direction, and to reducing the amount of needed antenna modules. A tightly-coupled dipole array exhibits wide operating frequency bandwidth characteristics.

Abstract: An antenna arrangement—comprising a differential mode antenna—and a common mode antenna, the antenna arrangement—comprising an antenna structure comprising one radiating element, at least one differential antenna feed configured to induce differential mode currents in the radiating element, and at least one common antenna feed configured to induce common mode currents in the radiating element. The antenna structure is configured to excite a first radiofrequency range and a second radiofrequency range in response to the differential mode currents and the common mode currents. The first antenna element and the second antenna element are configured to excite a third radiofrequency range in response to the differential mode currents or the common mode currents. This arrangement makes it possible to locate two antennas in the same given volume while maintaining a high level of isolation between the antennas.

Abstract: A mobile terminal includes a display, a side frame, a back cover and an antenna. The antenna includes a conductive support and a feeding part. The conductive support includes a first portion and a third portion disposed opposite to each other, and a second portion and a fourth portion disposed opposite to each other. The four portions are made of conductive materials and jointly enclose a cavity. The second portion is disposed on an inner side of the display. The third portion is a part of the side frame. The fourth portion is located on an outer side or an inner side of the back cover, or is a part of the back cover. A gap is disposed between the fourth portion and the first portion, or is disposed in the fourth portion, and the antenna can radiate electromagnetic wave signal through the cavity and the gap.

Abstract: A slot antenna comprising a first conductive structure, a second conductive structure, and an antenna feed coupled to the first conductive structure. The first conductive structure is wholly or partially enclosed by the second conductive structure and comprises a conductive surface and a non-conductive pattern. The non-conductive pattern comprises a longitudinal slot and a lateral slot extending at an angle from the longitudinal slot.
