Antenna device with surface antenna pattern integrally coated casing of electronic device
First Claim
1. An antenna device for using in an electronic device having an antenna module and a casing with an internal surface and an external surface, comprising:
- a surface antenna pattern, which is formed by film coating technology on the external surface of the casing of the electronic device for transceiving a wireless signal of a predetermined radiation frequency;
a signal guiding passage, comprising a signal feeding end for electrically connecting to the surface antenna pattern and a connecting end which passes through the casing to the internal surface of the casing and is electrically connected with the signal feeding line; and
an antenna signal feeding line, which is connected between the signal guiding passage and the antenna module of the electronic device for feeding the wireless signal transceived by the surface antenna pattern to the antenna module of the electronic device.

Abstract
An antenna device with a surface antenna pattern is formed either on an internal surface or on the external surface of a casing of an electronic device by film coating technology. The surface antenna pattern is either directly connected to a signal feeding line or connected to a signal feeding line through a signal guiding passage. In an embodiment, a recess is pre-formed on the external surface of the casing and then a surface antenna pattern is coated to the recess. The antenna device may further comprise an antenna coupling element arranged at the internal surface of the casing, in opposite to the surface antenna pattern. The antenna coupling element is inductively coupled with the surface antenna pattern for transceiving the signals to the electronic device.
