A multiple-beam antenna based on the principles of a folded reflectarray antenna and a bifocal antenna is presented. Experimental results are given for a 76.5 GHz antenna with 90 mm diameter, a heigh of 26 mm, and a scanning range of +/-13.5 as well as for an antenna with 130 mm diameter, a height of 30 mm, and a principle scanning range of +/-30 angle deg. With its low height and potentially low fabrication cost, this antenna is an interesting candidate for next generation automotive radars.
