In a horn antenna, with increase in aperture, the directivity is ____ and diffraction is ______ Correct Answer increased, decreased

Horn antenna is designed to improve the directivity and reduce the diffractions. It is used to properly match the waveguide to a large radiating aperture by shaping transition gradually. So, reflections are also decreased.
