Abstract
A planar antenna fitted with a reflector of small shape and small depth. A reflector 21 of planar shape is provided at the rear face of a radiator 20 of planar shape made of a triangular loop element. The side sections 21b on both sides of the reflector 21 are bent towards the radiator 20 and the separation .alpha.2 between the leading edges of the side sections 21b and the side edges of the radiator 20 is thereby reduced. In this way, an excellent electrical characteristic of the planar antenna 2 fitted with a reflector and can be achieved by reducing the separation D2 of the radiator 20 and reflector 21.
