Classification: CPC H | IPC H

Claim 12:
13. A structure of a chip antenna comprising:
a substrate having external through holes, internal through holes, and a circuit layer electrically connected to the external through holes and the internal through holes, and the circuit layer comprising a first side circuit layer, a second side circuit layer, and an internal circuit layer between the first side circuit layer and the second side circuit layer,
a solder mask disposed on a front surface and a back surface of the substrate, and configured to cover the internal circuit layer of the circuit layer to form the solder mask, the solder mask partially exposes the internal circuit layer,
a recognition pattern layer disposed on the front surface of the substrate exposed between the solder mask and an external circuit to form the recognition pattern layer for recognizing directions or part numbers,
an electrode layer disposed on walls of the internal through holes which are exposed, parts of a short line which is exposed, the first side circuit layer which is exposed, the walls of the external through holes which are exposed, and the second side circuit layer which is exposed, to form the electrode layer of the chip antenna.
