## Abstract

The invention relates to a method for making a device comprising a transponder antenna, wherein the method comprises the steps of: making an assembly including a thin substrate carrying at least one antenna, the antenna having connection end portions bearing on the substrate at substrates locations. The substrate forms or includes a sheet- or strip-like adhesive body in contact with the antenna. The invention also relates to the resulting device.

## Claims

### Claim 1

A method for making a device comprising a transponder antenna, said method comprising:
making an assembly including a substrate carrying at least one antenna, the antenna comprising connection end portions bearing on the substrate at substrates locations, and
wherein the substrate forms or includes a sheet- or strip-like adhesive body in contact with the antenna.

### Claim 2 (depends on 1)

A method according to claim 1, wherein the substrate has a thickness of less than 90 μm.

### Claim 3 (depends on 1)

A method according to claim 1, further including a step of forming a cavity close to the connection end portions locations.

### Claim 4 (depends on 3)

A method according to claim 3, wherein the step of forming a cavity includes the cutting of a least a start and/or an end portion of an antenna run.

### Claim 5 (depends on 3)

A method according to claim 3, further including a step of inserting an electronic module at least partially into the cavity, with said module including contact pads positioned opposite the connection end portions of the antenna.

### Claim 6 (depends on 3)

A method according to claim 3, further including a step of connecting the contact pads corresponding to the connection end portions after insertion into the cavity.

### Claim 7 (depends on 1)

A method according to claim 1, wherein the adhesive is used at a softening temperature of approximately 90 to 110° C.

### Claim 8

A device including a substrate carrying at least one antenna, with the antenna comprising:
connection end portions bearing on the substrate at substrates locations, wherein the substrate forms or includes a sheet- or strip-like adhesive body in contact with the antenna.

### Claim 9 (depends on 8)

A device according to claim 8, wherein the substrate has a thickness of less than 90 μm.

### Claim 10 (depends on 8)

A device according to claim 8, wherein the antenna with the connection end portions thereof is made by inlaying wire into the substrate.

### Claim 11 (depends on 8)

A device according to claim 8, further including:
a cavity close to the connection end portions locations, and
an electronic module at least partially positioned in the cavity, with said module including contact pads positioned opposite connection end portions of the antenna.

### Claim 12 (depends on 11)

A device according to claim 11, wherein the antenna wire and the connection end portions thereof are at least partially embedded in the adhesive substrate.

### Claim 13 (depends on 8)

A device according to claim 8, wherein the adhesive body has sufficiently poor mechanical and/or chemical behaviour properties to decompose or to tear in case of an attempted delamination of the covering sheet.

### Claim 14 (depends on 8)

A device according to claim 8, wherein the adhesive has a softening temperature of approximately 90 to 110° C.

### Claim 15 (depends on 8)

A radiofrequency communication electronic device, including the device according to claim 8.

### Claim 16 (depends on 15)

The radiofrequency communication electonic device of claim 15, wherein the device is a contactless chip card.

### Claim 17 (depends on 15)

The radiofrequency communication electronic device of claim 15, wherein the device is a passport.
