Electronic device with antenna

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.
