Embodiment Construction

[0032] According to a preferred embodiment of the invention, conductive ITO (Indium Tin Oxide) is used in order to form an antenna geometry invisible on the display and to form filters with the same material to optimize the antenna characteristics and frequency range.

[0033] Depending on whether a metal display frame, a metal display face, or a metal face behind the display is used as a ground reference, the geometry of the antenna and the connection point (i.e., the tap point for connection to the receiver) will vary.

[0034] exist Figure 1a and Figure 1b Two examples of dipole antenna structures are shown in , which can be realized by ITO printing.

[0035] In addition, in Figure 2a and Figure 2b An example of the patch antenna structure is shown in image 3 The slot helical antenna structure is shown in .

[0036] A slotted spiral is a typical arrangement of horizontally or vertically polarized omnidirectional transmitters as antennas in low-cost radar equipment...

Abstract

The device has a thin metal layer applied on a film of a display screen to ensure characteristics of an antenna and a filter, where the thin metal layer is made of tin oxide or indium. Vapor is deposited on the thin metal layer. The thin metal layer and the display screen are provided with an electronic filter. A spiral plane is provided with a circular radiating element that is arranged vertically or horizontally with the polarized antenna.

Description

technical field [0001] The invention relates to a device for receiving signals, in particular WLAN signals and Bluetooth signals, according to the preamble of claim 1 . Background technique [0002] There is an increasing need or demand for metal-encapsulated devices such as car radios, navigation devices, head units, PDAs, and mobile systems to supply Bluetooth signals, radar signals, or WLAN signals. [0003] For such devices with a metal housing, this means that an external receiving antenna, that is to say protruding from the metal housing, must always be provided. [0004] Usually this means that the antenna protrudes from the metal housing through the printed circuit board, but is arranged, for example, behind a device front / device housing part made of plastic. In the case of expensive devices with metal or plastic front panels with a metal surface, only pluggable antennas remain as a solution. [0005] A pluggable external antenna which is also conceivable but which...
