Offset Paraboloidal Reflector Antenna for Vehicular Collision Avoidance Radar

An offset paraboloidal reflector antenna for vehicular collision avoidance radar is designed and evaluated. The antenna is designed to use at 77GHz band, and to have suitable gain and beamwidth for the vehicular collision avoidance radar. The properties measured and calculated are compared and confirmed to agree well.

The offset paraboloidal reflector antenna is low-loss and has large degree of freedom of antenna design, compared with such as a microstrip antenna. So, using this type of the antenna for the radar system contributes to miniaturize, to make light weight, and to be easily mass-produced of the radar system.
