| 1. A planar horn array antenna, comprising:
a waveguide part;
a horn part having one side connected to the waveguide part and the other side formed with an opening for guiding a radio
wave incident or emitted thereto; and
a radio wave guide part having a dividing member coupled with the opening, the dividing member comprising circular dividing
holes arranged in a matrix of n×n, the radio wave guide part further having a cover member coupled between the opening and
the dividing member to cover the opening,
wherein in the cover member, when a wavelength of a radio wave incident or emitted to the dividing holes is λ, a thickness
of the cover member between the opening and the dividing member is formed to be equal to or less than λ/2.
