Abstract: A display assembly, a client device having the display assembly, and a method of manufacturing the display assembly are disclosed. Antenna performance in, e.g., mobile devices is improved via a robust and multifunctional multi-layer glass structure for a display of the mobile device or the like which allows placing auxiliary antenna elements between layers of the display structure. The structure allows placing the auxiliary antenna elements at different positions within it. The auxiliary antenna elements can be placed under and/or within the display, instead of, for example, surrounding the display. The multi-layer structure is continuous from the display surface to the substrate and gives freedom to place the auxiliary antenna elements, including metal elements, between any layers of the structure.

Abstract: An antenna arrangement comprising a dielectric element, at least one conductive element, an antenna radiator, and a plurality of exciter elements. The antenna radiator arranged at a first surface of the dielectric element and at a distance from the conductive element such that a gap is formed between the antenna radiator and a first surface of the conductive element. The exciter elements extend at least partially through a gap and are arranged on or adjacent to the conductive element. The antenna radiator may comprise a conductive material and be printed, sintered, painted, laminated, or deposited onto the first surface of the dielectric element, or molded into the dielectric element.

Abstract: A redirection structure for electromagnetic waves includes a multilayer structure and at least one antenna element. The multilayer structure includes a first conductive element, a conductive substrate, and a dielectric substrate arranged between the first conductive element and the conductive substrate and forming a wave guide. The antenna element is arranged adjacent an edge of the multilayer structure at an interface, the electromagnetic waves at least partially propagating in the wave guide along a first direction. The redirection structure further includes at least one dielectric cavity arranged at a predefined distance from the interface along the first direction. The dielectric cavity extends in a second direction away from the dielectric substrate at least partially through the conductive substrate.

IPC: H01Q9/04
Abstract: An antenna arrangement for a communication device comprises a top conductive patch comprising at least a first coupling point and a second coupling point coupled to one or more feed circuits carrying a radio frequency (RF) signal to or from the top conductive patch. The RF signal has a first phase in the first coupling point and a second phase in the second coupling point. A first slot extends in the conductive patch between the first coupling point and the second coupling point. The antenna arrangement according enables a desired current distribution to be realized in the antenna in a controlled and systematic manner. A communication device includes such an antenna arrangement.

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 beam steering antenna structure comprising a printed circuit board and a conductive component, a first wall and a second wall of the printed circuit board being juxtaposed with a first surface of the conductive component, the second wall abutting and being galvanically connected to the first surface. A second surface of the conductive component extends at an angle from the first surface. A connecting surface extends between the first wall and the second wall such that a groove is formed, the groove being partially juxtaposed to the first surface. The groove comprises a first antenna array and a second antenna array transmitting or receiving, respectively, a first radiation beam and a second radiation beam having orthogonal polarizations. The second surface steers at least one of the first or second radiation beam in a direction away from or towards the connecting surface.
