Abstract

We design a $3\times 2$ -slot sub array antenna for millimeter-wave car radars in the 76 GHz band. A cavity is introduced and designed to reduce phase differences among the slots. We change the slot length, width, and spacing to improve the gain. The antenna is designed for a wide bandwidth to have double resonance by two reflection-suppressing walls in the feeding part. The measured antenna has a reflection below -10 dB across 76.4 GHz-82.0 GHz. The gain is 15.5 dBi and the sidelobe level is -15.5 dB at 78.5 GHz in the measurement.
用于毫米波汽车雷达的波导3\ × 2$槽子阵列天线
设计了一种用于76 GHz频段毫米波车载雷达的3 × 2槽子阵列天线。引入并设计了一个腔体来减小槽间的相位差。我们改变槽的长度、宽度和间距来提高增益。该天线采用宽频带设计,在馈电部分通过两道反射抑制壁实现双谐振。被测天线在76.4 GHz-82.0 GHz范围内的反射小于-10 dB。在78.5 GHz时,增益为15.5 dBi,旁瓣电平为-15.5 dB。
