Abstract

An antenna pattern frame according to an aspect of the invention may include: a radiator having an antenna pattern portion transmitting and receiving a signal; a ground portion extending from the antenna pattern portion; a connection portion connecting the antenna pattern portion and the ground portion to be arranged in different planes; and a radiator frame manufactured by injection molding on the radiator so that the antenna pattern portion may be provided on one side of the radiator frame and the connection terminal portion may be provided on the other side thereof, the radiator frame allowing the antenna pattern portion to be embedded in the electronic device case.

Claims

1. A electronic device case comprising:

a radiator having an antenna pattern portion transmitting and receiving a signal;

a ground portion extending from the antenna pattern portion;

a connection portion connecting the antenna pattern portion and the ground portion;

a radiator frame in which the radiator is embedded so that the antenna pattern portion is provided on one side of the radiator frame and a connection terminal portion is provided on the other side thereof; and

a case frame disposed on the radiator frame;

wherein the connection portion is provided by bending the radiator, the ground portion is provided by bending the connection portion, and the connection portion is provided through the radiator frame;

wherein the ground portion is supported by a ground portion support stepped with respect to the radiator frame.

2. The electronic device case of claim 1, wherein a contact pin hole is provided in the radiator so that a contact pin of a mold is inserted into the contact pin hole during an injection molding to prevent a movement of the radiator inside the mold.

3. The electronic device case of claim 1, wherein a guide pin hole is provided in the radiator so that a guide pin of a mold is inserted into the guide pin hole during an injection molding to thereby prevent a movement of the radiator inside the mold.

4. An electronic device, comprising:

the electronic device case of claim 1; and

a circuit board electrically connected to the radiator.
