Design of a Traveling Wave Slot Array on Substrate Integrated Waveguide for 24GHz Traffic Monitoring

In this paper, a traveling wave slot array on substrate integrated waveguide (SIW) for 24GHz traffic monitoring is designed. The antenna array achieves beam steering through controlling the longitudinal slot spacing. The main beam points at an angle of 20° and has the advantage of miniaturization, easily fabricated and low cost. Simulated result is verified in this design.
