摘要: Lower-limit frequency reflection characteristics of a horn antenna (2) are improved even though element spacing, of less than or equal to one wavelength, is a spacing at which grating lobes do not occur in an antenna radiation pattern. The horn antenna (2) includes a horn antenna (2) and a conductor grid (1) that divides an aperture A (4) of the horn antenna (2) in a grid pattern and that electrically connects to an inner surface of the horn antenna (2) at the aperture A (4) of the horn antenna. Width of the conductor grid (1) in a direction orthogonal to a horn antenna aperture plane differs from electrical length of the path of the horn antenna (2) of the conductor grid (1) portion at the frequency of power supplied to the horn antenna (2).
