Abstract

An electronic device with an antenna, according to the present invention, has a cone antenna comprising: a cone radiator which is provided between a first substrate and a second substrate, has the upper part thereof connected to the first substrate and the lower part thereof connected to the second substrate, and has an opening at the upper part; a metal patch formed on the first substrate and spaced apart from the upper opening; and a shorting pin formed to electrically connect the metal patch and a ground layer of the second substrate. The electronic device may further comprise a transceiver circuit which is connected to the cone radiator via a feed and controls so as to radiate a signal via the cone antenna. Accordingly, the size of the entire antenna can be minimized by arranging the metal patch on only one side of the upper opening of the cone antenna.

First claim

What is claimed is:

1. An electronic device having an antenna, the electronic device comprising:
a cone antenna comprising:
a first substrate;
a second substrate spaced apart from the first substrate by a predetermined gap and provided with a ground layer;
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 upper aperture on the upper part;
a metal patch disposed on the first substrate, and spaced apart from the upper aperture; and
a shorting pin disposed to electrically connect the metal patch and the ground layer of the second substrate;
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; and
a transceiver circuit connected to the cone radiator through a power feeder to control a signal to be radiated through the cone antenna,
wherein the metal patch is disposed 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.

2. The electronic device of claim 1 , wherein the shorting pin is defined as a single shorting pin 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.

3. The electronic device of claim 1 , further comprising:
the power feeder disposed on the second substrate, and configured to transmit the signal through a lower aperture,
wherein an end portion of the power feeder is defined in a ring shape to correspond to a shape of the lower aperture.

4. The electronic device of claim 3 , further comprising:
a fastener configured to be connected to the second substrate through an inside of the end portion of the power feeder,
wherein the second substrate on which the power feeder is disposed and the cone radiator are fixed through the fastener.

5. The electronic device of claim 1 , wherein the metal patch is disposed on both the one side and an opposite side corresponding to the one side so as to surround an entire region of the upper opening of the cone antenna.

6. An electronic device having an antenna, the electronic device comprising:
a cone antenna comprising:
a cone radiator configured to connect a first substrate and a second substrate spaced apart from the first substrate by a predetermined gap, and provided with an upper aperture and a lower aperture;
a metal patch disposed on the first substrate, and spaced apart from the upper aperture; and
a power feeder disposed on the second substrate, and configured to transmit a signal through the lower aperture;
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; 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 the metal patch is disposed 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.

7. The electronic device of claim 6 , wherein the cone antenna is implemented with a plurality of cone antennas disposed on an upper left, an upper right, a lower left and a lower right of the electronic device,
the electronic device comprising a processor that controls an operation of the transceiver circuit, and
wherein the processor controls the transceiver circuit to perform multi-input multi-output (MIMO) through the plurality of cone antennas.

8. The electronic device of claim 6 , further comprising:
a shorting pin that connects between the metal patch and a ground layer of the second substrate,
wherein an end portion of the power feeder is defined in a ring shape to correspond to a shape of the lower aperture.

9. The electronic device of claim 8 , wherein the shorting pin is defined as a single shorting pin 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.

10. The electronic device of claim 6 , further comprising:
a fastener configured to be connected to the second substrate through an inside of an end portion of the power feeder,
wherein the second substrate on which the power feeder is disposed and the cone radiator are fixed through the fastener.
