Horn Antennas
A horn antenna is used for collimating the beam of the radar frontend. The antenna gain, the half-power beamwidth (HPBW) and thus the beam spot is mainly dependent on the aperture size of the horn.
The antenna characteristic is affected by the aperture size which can be seen in the above three images.
