Abstract
A module comprising a base (20) supporting a planar capacitor, an antenna, and a microcircuit electrically connected to each other to form a resonant electrical circuit, the capacitor including on a first face of the base a first electrode (30, 301, 302, 303) and a second electrode (300) disposed on a second face opposite to said first face facing said first electrode, the second electrode and the first electrode having substantially the same shape. Each electrode has at least a first portion and a second portion disposed on either side of the turns (40) of said antenna.

A module comprising:
- a base supporting a planar capacitor, an antenna having turns, and a microcircuit electrically connected to each other to form a resonant electrical circuit,
- wherein the planar capacitor includes on a first face of the base a first electrode and a second electrode disposed on a second face opposite to said first face facing said first electrode, the second electrode and the first electrode having substantially the same shape,
- wherein each electrode has at least a first portion and a second portion disposed on either side of the turns of said antenna.
A device comprising:
- a module comprising:
- a base having a first face and a second face that is opposite the first face and supporting a planar capacitor, an antenna having turns, and a microcircuit electrically connected to each other to form a resonant electrical circuit;
- wherein the planar capacitor comprises a first electrode on the first face of the base and a second electrode on the second face of the base, wherein the second electrode and the first electrode have substantially the same shape;
- and
- wherein the first electrode and the second electrode each have a first portion and a second portion disposed on either side of the turns of the antenna.
A method of manufacturing a module comprising a base supporting a planar capacitor, an antenna having turns, and a microcircuit electrically connected to each other to form a resonant electrical circuit, the method comprising:
- forming, on a first face of the base, a first electrode;
- forming, on a second face opposite to said first face, a second electrode facing said first electrode, the second electrode and the first electrode having substantially the same shape;
- wherein each electrode has at least a first portion and a second portion disposed on either side of the turns of said antenna.
