Abstract
An antenna device includes a feeding line having a first conductor and a second conductor and an antenna element having a conductive flat plate in which a slit is formed. The conductive flat plate has first and second sides opposite to each other and a third side. The antenna element is divided into an antenna pattern portion and a ground pattern portion via the slit. The slit is configured with a first slit portion apart from a center line towards the first side, a second slit portion apart from the center line towards the second side, a third slit portion coupling the first slit portion with the second slip portion, and a cutting portion coupling the third slit portion with the third side.
