1. An electronic device having an antenna, the electronic device comprising:
first and second ground planes arranged on different layers of a multi-layer substrate and configured to be connected to each other through vias spaced a predetermined distance apart from each other;
a signal line arranged on the same plane as the first ground plane which is the upper one between the first and second ground planes; and
radiators configured to be electrically connected to the signal line and to radiate a signal,
wherein the first ground plane is disposed in one side portion and the other side portion of the signal line in a first section forming a transmission line, and is disposed in one side portion of the signal line in a second section which is a transition section between the transmission line and the radiators, thereby forming an asymmetrical transmission line,
wherein the second ground plane is disposed in one side portion and the other side portion of the signal line in the first section, and is disposed in the entire one side portion of the second section and part of the other side portion thereof, and
vias connecting the first ground plane and the second ground plane are disposed in the one side portion in the second section.
