An antenna device (10) of a consumer electronic product is formed on an
outer surface (302) of a shell (30) of the electronic product. The shell
of the consumer electronic product is adapted for forming an enclosure of
an electronic product. The antenna device extends on a planar plane and
is integrally formed with and is coated on the outer surface of the
shell. A method for making the antenna device includes: (A) providing a
consumer electronic product having a shell for forming the antenna device
on an outer surface thereof, the shell being adapted for enclosing
components of the consumer electronic product therein; (B) coating a
copper layer on the outer surface of the shell of the electronic product;
(C) forming circuitry out of the copper layer to form the antenna device.
