Abstract

[PROBLEMS] To provide a tapered slot antenna which performs transmission and reception via a tapered emission opening which is optimal for MIMO. [MEANS FOR SOLVING PROBLEMS]An antenna is formed by two or more emission elements each having a tapered emission opening. The emission element includes a reflector at the tip end of the tapered emission opening side. Since the reflector is formed at the tip end of the emission element, the tapered emission opening is formed both in the emission element and the reflector. Thus, it is possible to obtain an axis length required for a wide band.
