Abstract

The invention teaches improved, novel methods and materials for the production of antennas. The invention contemplates the use of Directly Electroplateable Resins for the production of these antennas. The unique suitability of Directly Electroplateable Resins to allow facile manufacture of the antennas desired using a broad range of processing and manufacturing approaches is demonstrated.

Claims

1. An intermediate article in the manufacture of multiple completed antennas, said completed antennas comprising electroplated metal, said intermediate article comprising multiple structural patterns, said multiple structural patterns defining at least portions of said completed antennas, at least a portion of said structural patterns comprising a polymeric a material capable of being coated with said electroplated metal and wherein said polymeric material is positioned on an insulating support web, said web being substantially planar and having a length far greater than width such that it can be conveyed through processing steps in a manner characterized as continuous.

2. The intermediate article of claim 1 wherein said multiple structural patterns are joined by a buss to provide electrical communication from said patterns to a source of cathodic potential.

3. The intermediate article of claim 2 wherein said buss comprises an electrically conductive polymer.

4. The intermediate article of claim 3 wherein said electrically conductive polymer of said buss comprises a Directly Electroplateable Resin.

5. The intermediate article of claim 1 wherein said structural patterns are characterized as having a low profile.
