Casing for a portable terminal
A mobile communication terminal comprises a case having internal and external surfaces. The mobile communication device further comprises a first layer formed over the external surface of the case, the first layer comprising conductors for allowing plating on the outer surface of the case; a second layer formed over the first layer, the second layer comprising an antenna pattern for transmitting and receiving radio signals corresponding to one or more frequency bands; a third layer formed over the second layer to protect the case; a circuit board configured to process signals conformable to the radio signals, wherein the circuit board is disposed within an inner surface of the case; and a connection unit formed through the case and configured to electrically connect the second layer to the circuit board.
1. A mobile communication terminal comprising:
a case having an internal surface and an external surface;
an antenna pattern positioned at the case and configured to transmit and receive radio signals corresponding to one or more frequency bands;
a protection layer formed over the antenna pattern to protect the antenna pattern;
a circuit board covered by the case and configured to process signals conformable to the radio signals;
a recess portion positioned at the case such that the antenna pattern extends into the recess portion; and
one or more connection pins formed from a conductive material and inserted into a hole formed through a recessed surface of the recessed portion, wherein:
a first end portion of at least one connection pin of the one or more connection pins is connected to the antenna pattern, and
a second end portion of the at least one connection pin is connected to the circuit board.
2. The terminal of claim 1 , further comprising:
a first layer formed as being over the external surface of the case, the first layer comprising conductors configured to allow plating on the external surface, the first layer printed using ink comprising conductors, the printed ink defining a pattern of formation for the conductors; and
a second layer formed over the first layer and comprising the antenna pattern.
3. The terminal of claim 2 , wherein the first layer further comprises a binder resin that adheres the conductors onto the external surface.
4. The terminal of claim 2 , wherein the second layer is plated on the first layer.
5. The terminal of claim 4 , wherein the second layer further comprises a metal.
6. The terminal of claim 2 , wherein the protection layer is formed over the second layer to protect the second layer.
7. The terminal of claim 6 , wherein the protection layer comprises a color that is similar to a color of the second layer.
8. The terminal of claim 2 , wherein the protection layer is formed as being over the second layer to form an outer surface of the case to protect the case.
9. The terminal of claim 8 , wherein the protection layer is hardened by radiation.
10. The terminal of claim 9 , wherein the protection layer comprises a coating material that covers the second layer and the outer surface in a first color.
11. The terminal of claim 1 , wherein the antenna pattern extends from the recessed surface to an inner circumferential surface that defines the hole formed through the recessed surface.
12. The terminal of claim 1 , wherein the one or more connection pins are further configured to at least partially contact the antenna pattern between both ends of the antenna pattern.
13. The terminal of claim 1 , wherein the first end portion of the one or more connection pins terminates at the recessed surface and the second end portion of the one or more connection pins is elastically presses against a connection terminal disposed on the circuit board.
14. The terminal of claim 1 , wherein:
the first end portion of the one or more connection pins terminates at the recessed surface;
the second end portion of the one or more connection pins protrudes from an inner surface; and
the circuit board comprises a connection terminal configured to press against the second end portion of the one or more connection pins.
15. The terminal of claim 1 , wherein the one or more connection pins define grounding and feeding paths with the circuit board.
16. The terminal of claim 1 , further comprising:
a cover configured to cover the antenna pattern; and
an accommodation chamber, formed at the external surface and mounted with a battery.
17. The terminal of claim 16 , wherein:
the external surface comprises:
a main surface defining the accommodation chamber, and
side surfaces that cross the main surface; and
a pattern of the antenna pattern is formed on at least the main surface or the side surfaces.
