Claims

[Scope of utility model registration request]

In an antenna device equipped with a pair of slits for power radiation, the length of each slit of the pair of slits is set to approximately 1/2 of the line wavelength, in order to output circularly polarized waves, the slits constituting the pair of slits are An antenna device characterized in that the pair of slits is configured in a modified V-shape so that the distance between the two slits is 1/4 of the line wavelength.
