a cone radiator provided between the first substrate and the second substrate, an upper part of which is connected to the first substrate, a lower part of which is connected to the second substrate, and provided with an aperture at the upper part;
a metal patch disposed on the first substrate, and spaced apart from the upper aperture;
a shorting pin disposed to electrically connect the metal patch and the ground layer of the second substrate;
a power feeder disposed on the second substrate, and configured to transmit a signal through a lower aperture; and
a dielectric configured in a cylindrical shape to surround the lower aperture; and
a transceiver circuit connected to the cone radiator through the power feeder to control a signal to be radiated through the cone antenna,
wherein an end portion of the power feeder is defined in a ring shape to correspond to a shape of the lower aperture, and
wherein the end portion of the power feeder and a lower region of a transmission line region connected to the end portion are filled without removing the ground layer of the second substrate.

2. The electronic device of claim 1 , wherein the dielectric is defined in a three-dimensional sector form from which the dielectric is partially removed in a predetermined angular range in a region where a transmission line of the power feeder is disposed.

3. The electronic device of claim 2 , wherein the dielectric in the three-dimensional sector shape is disposed above the end portion of the power feeder in the ring shape to reduce a ring diameter of the end portion of the power feeder and a diameter of the lower aperture.

4. The electronic device of claim 1 , wherein the shorting pin is defined as a single shorting pin vertically connected between the metal patch and the second substrate, and
a null of a radiation pattern of the cone antenna is prevented from being generated by the single shorting pin.

5. The electronic device of claim 4 , wherein the shorting pin is provided with a screw having a predetermined diameter configured to vertically connect between the metal patch and the second substrate, and
the shorting pin further comprises a second dielectric disposed to surround the screw corresponding to the shorting pin, and configured in a cylindrical shape having a predetermined diameter.

6. The electronic device of claim 1 , further comprising:
at least one non-metal supporter configured to vertically connect the first substrate and the second substrate so as to support the first substrate and the second substrate.

7. The electronic device of claim 1 , further comprising:
a third substrate disposed below the second substrate,
wherein the transceiver circuit is disposed on a bottom surface of the third substrate.

8. The electronic device of claim 7 , wherein a signal line is disposed on a rear surface of the third substrate corresponding to the filled ground layer of the second substrate, and
signal loss is reduced by the filled ground layer corresponding to the signal line.

9. The electronic device of claim 1 , wherein the cone antenna further comprises:
a plurality of outer rims configured to constitute the upper aperture of the cone antenna and to connect the cone antenna to the first substrate; and
a plurality of fasteners configured to connect the outer rims and the first substrate.

10. The electronic device of claim 1 , further comprising:

wherein the second substrate on which the power feeder is disposed and the cone radiator are fixed through the fastener.

11. The electronic device of claim 1 , wherein the metal patch is disposed only on one side so as to surround a partial region of an upper opening of the cone antenna to minimize a size of the cone antenna including the metal patch.

12. The electronic device of claim 1 , wherein the metal patch is disposed as a rectangular patch having an outer side shape in a rectangular form, and
an inner side shape of the rectangular patch is defined in a circular shape to correspond to a shape of an outer line of the upper aperture so as to allow a signal radiated from the cone antenna to be coupled through an inner side of the rectangular patch.

13. The electronic device of claim 1 , wherein the metal patch is disposed as a circular patch having an outer side shape in a circular form, and
an inner side shape of the circular patch is defined in a circular shape to correspond to an outer shape of the upper aperture so as to allow a signal radiated from the cone antenna to be coupled through an inner side of the circular patch.

14. A vehicle having an antenna, the vehicle comprising:
a cone antenna comprising:
a cone radiator provided between a first substrate and a second substrate, an upper part of which is connected to the first substrate, a lower part of which is connected to the second substrate, and provided with an aperture at the upper part;
