Abstract

Methods and systems of attaching a radio transceiver to an antenna. At least some of the illustrative embodiments are systems comprising an antenna and an integrated circuit configured to operate as a radio transceiver. The antenna comprises a ground plane having a first edge surface, and an active element having a second edge surface. The ground plane and the active element are retained together such that the first and second edge surfaces are substantially coplanar and form an antenna edge. The integrated circuit is configured to operate as a radio transceiver, and the integrated circuit is mechanically coupled to the edge of the antenna and electrically coupled to the active element.

Claims

1. A system comprising:

an antenna comprising;

a ground plane having a first edge surface on a perpendicular plane;

an active element having a second edge surface;

wherein the ground plane and the active element are retained together such that the first and second edge surfaces are substantially coplanar and form an antenna edge; and

an integrated circuit of a tag in communication with a reader, the integrated circuit configured to operate as a radio transceiver, the integrated circuit mechanically coupled to and supported on the antenna edge, and electrically coupled to the active element.

2. The system according to claim 1 wherein the integrated circuit is a radio frequency identification (RFID) circuit.

3. The system according to claim 1 wherein the integrated circuit is a bare die, and wherein the integrated circuit mechanically and electrically couples to the antenna edge by way of a controlled collapse chip connection.

4. The system according to claim 1 wherein the antenna is at least one selected from the group consisting of:

a patch antenna;

an inverted “

F”

patch antenna; and

a fractal antenna.

5. A method comprising:

providing an antenna having a ground plane with an edge on a perpendicular plane, and a top defined by a substantially planar active element; and

supporting by and attaching to the edge an integrated circuit configured to operate as a radio transceiver.

6. The method according to claim 5 wherein attaching further comprises attaching at least one selected from the group consisting of:

an RFID reader; and

an RFID circuit.

7. The method according to claim 5 wherein attaching further comprises:

adhering the integrated circuit being a bare die integrated circuit to the edge; and

electrically coupling by at least one selected from the group consisting of;

a wire bond;

and a controlled collapse chip connection.
