Abstract
To reduce the manufacturing cost by reducing the number of surfaces of a dielectric base on which various patterns are formed, and to improve the ease of impedance matching while avoiding an increase in size. Each of a feed electrode and a ground electrode is formed between a position on an end surface and a position on a lower surface of a dielectric base. A radiation electrode is formed, which extends from a position on an upper surface to positions on the upper and lower surfaces via another end surface of the dielectric base.
