Claims

[Scope of utility model registration request]

A tapered primary horn part whose diameter increases toward the front, a short circular linear polarization converter connected to the rear end of this tapered primary horn part, and a A linearly polarized wave of one side of the circularly polarized wave is input to or output from the primary horn part from the front end of the transformed part to the middle of the transformed part. A primary radiator characterized in that a pair of opposing planes are formed in a direction substantially parallel to the direction of the component.
