Embodiment Construction

[0027] The invention takes the form of an antenna 100 for near field communication comprising a conductive trace 102 having a graphic image 120 . exist Figure 1A and 1B An embodiment of the invention is shown in and in Figure 2A and 2B Another embodiment of the invention is shown in .

[0028] The conductive trace 102 defines the primary shape 110 of the antenna, which may take the form of a circular or rectangular helix, coil or other shape.

[0029] The spiral may be single or multiple, and may be a uniform and / or non-uniform curve that starts at a center point and then rotates around the center point while gradually moving away from the center point with each revolution. Instead the coils may be wires that change direction in a uniform and / or non-uniform manner.

[0030] The primary antenna shape may be formed by conductive traces 102, the length of which may be in the range of 300 mm to 1200 mm, in particular in the range of 400 mm to 1000 mm, preferably in the range...

Abstract

An antenna (100) for near-field communication including an electrically conducting track (102). This track (102) defines, by the pattern thereof, a primary shape of the antenna and includes an arrangement of primary portions (121) of the same width and of secondary portions (122) of different widths to that of the primary portions (121), such that the arrangement forms a figurative image (120) onthe antenna (100).

Description

technical field [0001] The technical field of the invention relates to the field of antennas, and more particularly to the field of near field communication antennas. Background technique [0002] Antennas for near field communication are known in the prior art. These antennas can be visible to the user, and the shape of the antennas can be modified to improve their visual appearance. [0003] However, after each modification to the antenna, the performance level of the antenna changes accordingly and the radio-frequency circuits used have to be re-adapted. [0004] A solution should be found which allows the aesthetic appearance of the antenna to be modified without adapting the radio frequency circuit used according to these modifications. Contents of the invention [0005] The present invention proposes to overcome all or some of these drawbacks by an antenna for near field communication comprising conductive tracks; said conductive tracks defining the primary shape o...
