Abstract
An antenna unit includes a plate-shaped dielectric substrate, as well as an antenna element and a stub element. The dielectric substrate has a first edge extending along a longitudinal direction of the dielectric substrate and a second edge extending along the longitudinal direction of the dielectric substrate, and the second edge is opposite to the first edge. The antenna element is disposed along the longitudinal direction of the dielectric substrate. The Antenna element has a first end containing a feedpoint and a second end containing an open end. The stub element is disposed between a section of the antenna element having a predetermined length containing the first end of the antenna element and the first edge of the dielectric substrate along the longitudinal direction of the dielectric substrate. The stub element has a first end connected to a reference potential and a second end containing an open end.
