Claims

[Scope of utility model registration request]

In a horn antenna having a partition plate that divides the horn antenna opening into at least two parts, when the equivalent tube wavelength in the horn antenna is λg, a second partition plate having substantially the same shape as the partition plate is provided in the horn antenna. A horn antenna characterized in that it is arranged at a position approximately λg/4 from the partition plate of the opening.
