Abstract :
Geometrical parameter of 1 horn, 1 parabolic, 4 Cassegrain and 1 offset-Cassegrain antennas for collision avoidance radar system in UAV are designed for the first time and then, the radiation patterns of these single-feed antennas are generated by S/W and compared. The sidelobes of the parabolic and the Cassegrain antennas are smaller than the others, however, the parabolic antenna is chosen for UAV because of simple manufacturing load and small size.
