Abstract

An electronic device case having an antenna pattern embedded therein includes: a radiator having an antenna pattern portion transmitting and receiving a signal and a connection terminal portion allowing the signal to be transmitted to and received from a circuit board of an electronic device; a connection portion partially forming the radiator and connecting the antenna pattern portion and the connection terminal portion to be arranged in different planes; a radiator frame manufactured by injection molding on the radiator so that the antenna pattern portion of the radiator is provided on one side of the radiator frame and the connection terminal portion is provided on the other side thereof; and a case frame covering the one side of the radiator frame on which the antenna pattern portion is provided so that the antenna pattern portion is embedded between the case frame and the radiator frame.

Claims

1. A case of an electronic device including a circuit board, the case comprising:

a radiator including an antenna pattern portion configured to transmit and receive a signal;

a connection terminal separated from the antenna pattern portion and including a connection terminal portion configured to transmit and receive the signal of the antenna pattern portion to and from the circuit board of the electronic device;

an injection-molded antenna pattern frame including the antenna pattern portion on one side, the connection terminal portion on the other side, wherein the radiator and the connection terminal are brought into contact with each other; and

a case frame configured to cover the one side of the antenna pattern frame including the antenna pattern portion, wherein the antenna pattern portion is embedded between the case frame and the antenna pattern frame.

2. A mobile communications terminal, comprising a case including an embedded antenna pattern, the case comprising:

a radiator including an antenna pattern portion configured to transmit and receive a signal;

a connection terminal separated from the antenna pattern portion and including a connection terminal portion configured to transmit and receive the signal of the antenna pattern portion to and from a circuit board of an electronic device;

an injection-molded antenna pattern frame including the antenna pattern portion on one side, the connection terminal portion on the other side, wherein the radiator and the connection terminal are brought into contact with each other; and

a case frame configured to cover the one side of the antenna pattern frame including the antenna pattern portion, wherein the antenna pattern portion is embedded between the case frame and the antenna pattern frame.
