Embodiment Construction

[0053] Figures 1 to 6 show the antenna arrangement of the present invention in its various stages of manufacture.

[0054] Figure 1a A plan view of the upper side of the printed circuit board 10 is shown comprising an upper side and a lower side, on which in each case a copper layer 14 is applied. Figure 1a Holes 12 for interconnections 22 (vias) between circuit components on the upper side and circuit components on the lower side of the printed circuit board 10 are shown. Via holes 12 may be produced, for example, by a drilling or milling process. The side walls 11 of the printed circuit board 10 define via holes 12 .

[0055] Figure 1b to follow Figure 1a The way of the cross section of the line A-A' is shown Figure 1a the printed circuit board 10. In addition to the via holes 12 , copper layers 14 , 14 ′ can also be seen, which are in each case applied to the upper and lower sides of the printed circuit board 10 . exist Figure 1b In and in the remaining cross-sect...

Abstract

The invention relates to an antenna assembly. The present invention relates to an antenna arrangement with a printed circuit board, which has an upper side and a lower side, and an antenna supported by the printed circuit board, in particular ring antenna, which comprises at least one electrically conductive antenna section which is arranged on a narrow side of the printed circuit board adjoining the upper side and / or the lower side. The invention also relates to a process for producing an antenna arrangement which comprises a printed circuit board with an upper side and a lower side and an antenna supported by the printed circuit board, in which process for forming at least one antenna section, an electrically conductive material is attached to a narrow side of the printed circuit board which adjoins the upper side and / or the lower side.

Description

technical field [0001] The present invention relates to an antenna device having a printed circuit board and an antenna supported by the printed circuit board. Background technique [0002] Such antenna arrangements are known in principle and are used, for example, as transmitting antennas in hand-held transmitters or electronic keys that can be used, for example, to lock and unlock motor vehicles or to open and close garage doors, for example by remote control. . [0003] Known antenna arrangements have proven to be disadvantageous because they have a relatively low antenna efficiency. That is, the transmit power of the available antenna broadcast is relatively low compared to its required antenna power input. [0004] In known antenna arrangements, this often results in low range and high energy requirements for the antenna or in a correspondingly low battery life. SUMMARY OF THE INVENTION [0005] It is therefore an object of the present invention to provide an anten...
