HORN ANTENNA

Document Type and Number:

WIPO Patent Application WO/2016/194888

Kind Code:

A1

Abstract:

In order to improve a reflection characteristic at a lower limit frequency even in the case of an interelement spacing of one wavelength or less at which a grating lobe does not occur in an antenna radiation pattern in a horn antenna (2), the horn antenna (2) is provided with: the horn antenna (2); and a conductor grid (1) that is electrically connected to the inner surface of the horn antenna (2) in an aperture A (4) of the horn antenna and divides the aperture A (4) of the horn antenna (2) in a grid pattern. In the conductor grid (1), the width in a direction orthogonal to a horn antenna aperture plane of the conductor grid (1) and the electric length at a frequency at which power is fed to the horn antenna (2) of the path of the horn antenna (2) in the conductor grid (1) portion are different.
