Abstract

A touch panel having hidden antenna has a multi-layer body and at least one antenna unit. The multi-layer body has a first electrode, a second electrode and an intermediate layer sandwiched by the first electrode and the second electrode. The at least one antenna unit is mounted on different positions inside the multi-layer body to constitute a plane antenna or a three-dimensional antenna. Accordingly, hidden inside the multi-layer body, the at least one antenna unit is not prone to defacement and damage, occupies little space, has a good communication quality and is durable.

Claims

1. A touch panel having hidden antenna, comprising:

a multi-layer body having a second electrode, an intermediate layer and a first electrode sequentially stacked from a bottom to a top of the multi-layer body; and

at least one antenna unit mounted inside the multi-layer body;

wherein the intermediate layer has a top surface, a bottom surface and four sides.

2. The touch panel as claimed in claim 1, wherein each of the at least one antenna unit is mounted on the top surface of the intermediate layer.

3. The touch panel as claimed in claim 1, wherein each of the at least one antenna unit is mounted on the bottom surface of the intermediate layer.

4. The touch panel as claimed in claim 1, comprising multiple antenna units respectively mounted on a perimeter of the top surface and the sides of the intermediate layer, wherein each antenna unit mounted on a corresponding side of the intermediate layer adjoins another adjacent antenna unit mounted on the top surface of the intermediate layer to constitute a first three-dimensional antenna.

5. The touch panel as claimed in claim 1, comprising multiple antenna units respectively mounted on a perimeter of the bottom surface and the sides of the intermediate layer, wherein each antenna unit mounted on a corresponding side of the intermediate layer adjoins another adjacent antenna unit mounted on the bottom surface of the intermediate layer to constitute a second three-dimensional antenna.

6. The touch panel as claimed in claim 1, comprising multiple antenna units respectively mounted on a perimeter of the top surface, a perimeter of the bottom surface and the sides of the intermediate layer, wherein each antenna unit mounted on a corresponding side of the intermediate layer adjoins two adjacent antenna units respectively mounted on the top surface and the bottom surface of the intermediate layer to constitute a third three-dimensional antenna.
