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 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; and a radiator frame manufactured by injection molding on the radiator so that the antenna pattern portion is provided on one side of the radiator frame and the connection terminal portion is provided on the other side thereof while the antenna pattern portion is embedded in the electronic device case.

Claims

1. An antenna pattern frame, comprising:

a radiator having

an antenna pattern portion configured to transmit and receive a signal,

a connection terminal portion configured to transmit and receive the signal to and from a circuit board of an electronic device, and

a connection portion such that the antenna pattern portion and the connection terminal portion are arranged in different planes from each other; and

a radiator frame configured to embed the radiator therein, such that the antenna pattern portion is exposed on a first surface of the radiator frame, the radiator frame configured for insertion into a recess defined between an outer case of the electronic device and the circuit board of the electronic device, to retain the antenna pattern portion between an inner surface of the outer case of the electronic device and the radiator frame,

wherein the connection portion connects the antenna pattern portion with the connection terminal portion,

wherein the radiator frame further comprises a protrusion, wherein the connection portion is embedded through the protrusion perpendicular to the second surface, the connection portion extending beyond the protrusion of the radiator frame and coupling to the connection terminal portion which extends parallel to the second surface in spaced relation in a direction opposite from the antenna pattern portion.

2. The antenna pattern frame of claim 1, wherein the second surface of the radiator frame has a curved shape.

3. The antenna pattern frame of claim 1, wherein the exposed surface of the antenna pattern portion is substantially continuous with the first surface of the radiator frame.

4. The antenna pattern frame of claim 1, wherein the radiator frame has a hole penetrating through the radiator frame perpendicular to the second surface, and the connection portion extends through the hole.

5. The antenna pattern frame of claim 1, wherein the connection terminal portion extends from one end of the connection portion along the second surface.

6. The antenna pattern frame of claim 5, wherein

the connection terminal portion extends in a direction that does not overlap with the antenna pattern portion.

7. The antenna pattern frame of claim 1, further comprising:

a contact surface extension protruding from the antenna pattern portion, and configured to securely fix the radiator to the radiator frame.

8. The antenna pattern frame of claim 1, wherein the radiator frame is further configured to be retained between the outer case and the circuit board of the electronic device.
