1. An electronic device having an antenna, the electronic device comprising:
a plurality of transparent antennas embedded into different regions of a display and configured to radiate corresponding signals to a front of the display;
a transmission line that feeds each of the plurality of transparent antennas,
wherein each of the plurality of transparent antennas includes a feeding line and a ground region disposed in a left region and a right region of the feeding line, and
wherein each of the plurality of transparent antennas is configured in the form of a rectangular patch antenna that is rotated at a predetermined angle, and
wherein, in a first rectangular patch antenna of the plurality of transparent antennas, portions of a left region and a right region of the first rectangular patch antenna are cut so as to form straight vertical lines, and a top region of the first rectangular patch antenna is cut, so as to convert the first rectangular patch antenna into a first heptagon patch antenna,
wherein the straight vertical lines are in a direction perpendicular to a current direction of the corresponding ground region,
wherein, in a second rectangular patch antenna of the plurality of transparent antennas, portions of a left region and a right region of the second rectangular patch antenna are cut so as to form opposing curved lines, and a top region of the second rectangular patch antenna is cut, so as to convert the second rectangular patch antenna into a second heptagon patch antenna having two opposing curved sides,
wherein the opposing curved lines of the second heptagon patch antenna are in a direction perpendicular to a current direction of the corresponding ground region.
