Abstract: A transmission line for transmitting radiofrequency range current between a first conductive element and a second conductive element, the transmission line comprising a signal current line and at least one return current line, the signal current line and the return current line(s) extending in parallel. Each current line comprises at least one first segment and at least one second segment.

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 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.
