Abstract
Provided is a tag integrated circuit (IC) module apparatus and a method of fabricating tag IC module apparatus. The tag IC module apparatus may include an n-turn loop coil, n denoting a natural number, connected in series with a tag IC, and a printed circuit board (PCB) disposed below the tag IC and patterned with the n-turn loop coil.
Claims11
A tag integrated circuit (IC) module apparatus, comprising:
- an n-turn loop coil connected in series with a tag IC, n denoting a natural number;
- and
- a first printed circuit board (PCB) disposed below the tag IC and patterned with the n-turn loop coil;
- wherein the tag IC is disposed over opposite ends of the coil on an upper surface of the PCB and connects the opposite ends across a gap separating the opposite ends;
- wherein the n-turn loop inductively couples an induced radio frequency (RF) signal to a metal body and transfers the induced RF signal to the tag IC when the tag IC module apparatus is attached to the metal body.

A method of fabricating a tag integrated circuit (IC) module apparatus, the method comprising:
- patterning an n-turn loop coil on a printed circuit board (PCB), n denoting a natural number;
- disposing the PCB below a tag IC, and connecting the tag IC between opposite mounting electrodes on an upper surface of the PCB across a gap separating the opposite mounting electrodes to connect the tag IC with the n-turn loop coil in series;
- and
- attaching the tag IC module apparatus to a metal body for the n-turn loop coil to inductively couple an induced radio frequency (RF) signal to the metal body and transfer the induced RF signal to the tag IC.
