Abstract
In a method of manufacturing an antenna (11) formed on a substrate (1) an antenna structure (2) is formed on the substrate (1). The antenna structure (2) comprises an area (3) which initially is electrically short-circuited and is designed to be turned into an antenna contact (4a,4b) to be contacted with contacts (12,13) of an integrated circuit (IC). The antenna contact (4a,4b) is formed by mechanically separating the electrically short-circuited 5 area (3) particularly utilizing cutting or stamping means (5).
Claims12
A method of manufacturing an antenna formed on a substrate, comprising the steps of:
- forming an antenna structure on a substrate, the substrate including a continuous area;
- and
- forming a cross-shaped structure including antenna contact pads and a die landing area by forming a cross-shaped cut in the continuous area and stretching the substrate to widen the cross-shaped cut to form the cross-shaped structure.
A method of manufacturing a strap accommodating an integrated circuit, comprising the steps of:
- forming a conductive structure on a strap substrate;
- forming a cross-shaped structure including strap contacts by forming a cross-shaped cut in the conductive structure and stretching the strap substrate to widen the cross-shaped cut to form the cross-shaped structure;
- forming optical alignment markers on the strap substrate;
- and
- placing an integrated circuit on the strap substrate using the optical alignment markers to assist in mounting of the integrated circuit.
A strap for accommodating an integrated circuit comprising:
- a strap substrate;
- optical alignment markers on the substrate configured and arranged to assist in an antenna alignment;
- and
- a conductive structure formed on the strap substrate including strap contacts configured and arranged to contact an integrated circuit and gaps, the gaps and the strap contacts forming a mechanically separated cross-shaped structure and the conductive structure being configured and arranged to contact an antenna.
