Abstract

The disclosure relates to a flexible printed circuit board of longitudinal shape comprising at least one conductive track extending over the length of the flexible printed circuit, the flexible printed circuit board comprising at least one folding area shaped so as to allow said flexible printed circuit board to pass from an unfolded state to a folded state in which the conductive track forms at least one antenna loop.

First claim

The invention claimed is:

1. An elongate flexible printed circuit board comprising:
at least two conductive tracks extending over a length of the elongate flexible printed circuit, the at least two conductive tracks being substantially parallel to each other; and
at least one folding area shaped so as to allow said elongate flexible printed circuit board to pass from an unfolded state to a folded state,
in the unfolded state a first end of the elongate flexible printed circuit board is spaced from a second end of the elongate flexible printed circuit board,
in the folded state the first end of the elongate flexible printed circuit board overlays the second end of the elongate flexible printed circuit board such that the at least two conductive tracks form at least one antenna loop.

2. The elongate flexible printed circuit board of claim 1 , wherein at least one of the first and second ends of the elongate flexible printed circuit board comprises means for connecting said at least two conductive tracks to each other in order to form the at least one antenna loop.

3. The elongate flexible printed circuit board of claim 1 , further comprising a connection extension for connecting the at least one antenna loop to an appropriate connector.

4. The elongate flexible printed circuit board of claim 1 , further comprising at least one orifice for affixing said elongate flexible printed circuit board to at least one antenna support.

5. The elongate flexible printed circuit board of claim 1 , wherein at least one of the first and second ends of the elongate flexible printed circuit board comprises a connector for connecting said at least two conductive tracks to each other in order to form the at least one antenna loop.

6. A device comprising:
a transceiver; and
an antenna, the antenna comprising an elongate flexible printed circuit board, the elongate flexible printed circuit board comprising:
at least two conductive tracks extending over a length of the elongate flexible printed circuit, the at least two conductive tracks being substantially parallel to each other; and
at least one folding area shaped so as to allow said elongate flexible printed circuit board to pass from an unfolded state to a folded state,
in the unfolded state a first end of the elongate flexible printed circuit board is spaced from a second end of the elongate flexible printed circuit board,
in the folded state the first end of the elongate flexible printed circuit board overlays the second end of the elongate flexible printed circuit board such that the at least two conductive tracks form at least one antenna loop.

7. The device of claim 6 , wherein at least one of the first and second ends of the elongate flexible printed circuit board comprises means for connecting said at least two conductive tracks to each other in order to form the at least one antenna loop.

8. The device of claim 6 , wherein the elongate flexible printed circuit board further comprises a connection extension for connecting the antenna to an appropriate connector.

9. The device of claim 6 , further comprising at least one antenna support; and
wherein the elongate flexible printed circuit board further comprises at least one orifice for affixing said elongate flexible printed circuit board to the at least one antenna support.

10. The device of claim 6 , wherein at least one of the first and second ends of the elongate flexible printed circuit board comprises a connector for connecting said at least two conductive tracks to each other in order to form the at least one antenna loop.

11. The device of claim 6 , further comprising at least one supporting part on which said antenna is positioned.
