Analysis and Design of Multi-Band Microstrip Array Antennas for Millimeter-wave Radar System

In this paper, we have designed the patch array antennas with the slots capable of working in millimeter-wave radar system. The designed array antennas have multi-band characteristics at 77GHz. As a result, this paper is proposed the possibility of prototyping by design and analysis of microstrip array antennas for mm-wave radar as using a patch arrays with U-shaped slots.
