## Abstract

Disclosed is a radiator frame and a method of manufacturing the radiator frame. The radiator frame includes a radiator comprising an antenna pattern configured to transmit or receive a signal and a terminal connection configured to electrically connect the antenna pattern to a circuit board, and a molding frame configured to embed the radiator, wherein the antenna pattern is embedded in a first surface of the molding frame, and the terminal connection is exposed to a second surface of the molding frame.

## Claims

### Claim 1

A radiator frame comprising:
a radiator comprising an antenna pattern configured to transmit or receive a signal and a terminal connection configured to electrically connect the antenna pattern to a circuit board; and
a molding frame configured to embed the radiator,
wherein the antenna pattern is embedded in a first surface of the molding frame, and
the terminal connection is exposed to a second surface of the molding frame.

### Claim 2 (depends on 1)

The radiator frame of claim 1, wherein a supporting groove is provided in a portion of the second surface of the molding frame.

### Claim 3 (depends on 1)

The radiator frame of claim 1, wherein the antenna pattern is embedded in the molding frame to be spaced apart from one surface of the molding frame by about 0.2 mm.

### Claim 4 (depends on 1)

The radiator frame of claim 1, wherein the radiator is embedded in the molding frame by injection-molding a resin.

### Claim 5 (depends on 1)

The radiator frame of claim 1, wherein the antenna pattern is embedded in the molding frame to be spaced apart from one surface of the molding frame by about 0.2 mm to 0.5 mm.

### Claim 6 (depends on 1)

The radiator frame of claim 1, wherein the antenna pattern and the terminal connection are disposed in different planes.

### Claim 7

A mold for manufacturing a radiator frame, the mold comprising:
an upper mold comprising at least one guide pin;
a lower mold including a supporting pin, and the lower mold combines with the upper mold to provide an internal space to accommodate a radiator comprising an antenna pattern; and
a resin injector provided in at least one of the upper mold and the lower mold to inject a resin into the internal space;
wherein the at least one guide pin and the supporting pin fix the antenna pattern in the internal space, and
the at least one guide pin combines with an elastic part to be retractable by a pressure of the resin injected into the internal space.

### Claim 8 (depends on 7)

The mold of claim 7, wherein the elastic part comprises:
an elastic member configured to have a first end attached to the guide pin;
a support member configured to support a second end of the elastic member;
a guide hole provided in the upper mold, and
the at least one guide pin is inserted into the guide hole and a end of the at least one guide pin exposed to the internal space.

### Claim 9 (depends on 8)

The mold of claim 8, wherein the elastic member is a spring.

### Claim 10 (depends on 8)

The mold of claim 8, wherein the quantity of the elastic member is equal to a quantity of the at least one guide pin.

### Claim 11 (depends on 7)

The mold of claim 7, wherein the supporting pin protrudes into the internal space.

### Claim 12 (depends on 7)

The mold of claim 7, wherein the upper mold has a groove of about 0.2 MM.

### Claim 13 (depends on 8)

The mold of claim 8, wherein the end of the at least one guide pin exposed to the internal space is retracted in the guide hole, in response to the pressure of the injected resin.

### Claim 14 (depends on 13)

The mold of claim 13, wherein the at least one guide pin does not protrude into the internal space.

### Claim 15 (depends on 13)

The mold of claim 13, wherein the pressure of the resin injected into the internal space is sufficient to compress the elastic member.
