Dual Band Slotted Antenna for Radar and Automotive Applications

This paper present the design of a new rectangular microstrip patch antenna on a low resistivity silicon substrate fed by mi- crostripline to operate for millimeter band applications. The slots are used to achieve good impedance matching to increase bandwidth. The proposed antenna is designed and optimized based on 3D EM simulations studies, presents a low profile dual band antenna with small size of 0.64mm1 mm operating at 60 GHz and 77 GHz with a relatively significant gain for radar applications and communication at very high speed in an automotive environment.
