Abstract

An intermediate product for the manufacture of an antenna includes a pressure sensitive adhesive, one or more stamped traces bonded with the pressure sensitive adhesive, and at least one tie-bar connected between the one or more traces. The at least one tie-bar supports the one or more traces. The one or more traces can be stamped from a sheet of copper. The pressure sensitive adhesive can be a pressure sensitive adhesive pad having more than one pressure sensitive adhesive area.

Claims

1. An intermediate product for the manufacture of an antenna, comprising:

a pressure sensitive adhesive having at least one die cut hole; and

an antenna biscuit including one or more stamped traces, at least one tie-bar connected between the one or more traces, and at least one pilot hole,

wherein the at least one tie-bar supports the one or more traces, and the at least one die cut hole and the at least one pilot hole facilitate alignment of the antenna biscuit and the pressure sensitive adhesive such that a pressure sensitive adhesive area of the pressure sensitive adhesive is positioned on the one or more stamped traces.

2. The intermediate product of claim 1, wherein the one or more traces are stamped from a sheet of copper.

3. The intermediate product of claim 1, wherein the pressure sensitive adhesive is a pressure sensitive adhesive pad having more than one pressure sensitive adhesive area.

4. The intermediate product of claim 3, wherein the pressure sensitive adhesive pad comprises one or more non-adhesive areas separating the pressure sensitive adhesive areas.

5. The intermediate product of claim 3, wherein the pressure sensitive adhesive areas are shaped to match the shape of the one or more stamped traces.

6. The intermediate product of claim 1, comprising a carrier connected to the one or more stamped traces.

7. The intermediate product of claim 6, wherein the at least one pilot hole extends through the carrier.

8. The intermediate product of claim 1, comprising a release liner positioned over the antenna biscuit, the antenna biscuit being positioned between the release liner and the pressure sensitive adhesive.

9. The intermediate product of claim 8, wherein the release liner is removed from the pressure sensitive adhesive prior to being positioned over the antenna biscuit.

10. The intermediate product of claim 1, wherein the antenna biscuit and the pressure sensitive adhesive are positioned on a fixture such that they can be transferred to a station.
