Abstract: The disclosure relates to suppressing surface waves in a communication device for a wireless communication system. The communication device includes a dielectric layer extending along a plane between a chassis and a glass layer, an antenna element configured to emit a radio wave, and a retroreflective structure extending inside the dielectric layer and being located adjacent to the antenna element, and where the retroreflective structure is configured to reflect the radio wave in an angle non-parallel to the plane. The retroreflective structure hence prevents parasitic channeling of the antenna energy into surface waves in and behind the glass layer and directs the radiation into the desired direction.

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.

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: 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.
