Abstract
A tapered slot antenna includes a dielectric sheet, a conductor layer laminated on said dielectric sheet, in which conductor layer a tapered slot pattern is formed as a result of a slot width of a slotline being widened gradually, and corrugated structures provided at two sides of said conductor layer, parallel to a direction in which an electromagnetic wave is radiated from said antenna. The shape of said antenna is axially asymmetrical.
