Microstrip Array Antenna for 24GHz Short-Range Automotive Radar
In recent years, active driving assistance system is becoming more and more popular, and automotive radar is the key part of the active driving assistance system, which can judge the speed and distance of other vehicles around the vehicle. In this paper, a short-range automotive radar microstrip array antenna working at 24 GHz is designed. The antenna is composed of 12 × 2 antenna elements. The antenna size is 88.76 mm × 17.16 mm. By simulating the antenna in CST simulation software, the resonant frequency is 24.02 GHz and the reflection coefficient is -33.18 dB, the gain of the antenna is 19.4 dB, the half-power beam width on the E-plane is 8.4°. The side lobe levels on E-plane and H-plane are -20.0 dB and -21.4 dB respectively. The antenna has good side lobe level performance.
