In this paper a reduced size planar grid array antenna for automotive radar sensor applications, operating in the 77-81 GHz frequency band is introduced. Antennas for this type of application must be low in cost, be quickly produced, and fit within the available mounting locations. The proposed antenna is composed by reduced size loop elements. Planar differential microstrip line is used to feed the central element. The single row offers a narrow beam in elevation and a wide beam in azimuth. Compared to other automotive radar configurations, this antenna design is a completely planar antenna based on a low-cost fabrication technology. A size reduction of 55% has been achieved. © 2015 EurAAP.
