摘要

本文提出了两种用于79 GHz汽车频段的紧凑型槽阵天线，它们集成在28 um厚的苯并环丁烯(BCB)衬底上，并附着在325 um厚的5-20 Ωcm块电阻硅晶片上。两个天线分别是发射(TX) 1×8槽阵天线，尺寸为1×23 mm，接收(RX) 8×8槽阵天线，尺寸为15×23 mm。在70-90 GHz频率范围内，TX和RX子阵列天线(增益>4 dBi)与50 Ω (RL>10 dB)匹配良好，性能良好。通过在天线背面安装一个金属腔，可以减少平行板模式，并将增益提高2dB。实测结果与模拟结果基本一致。

Compact integrated slot array antennas for the 79 GHz automotive band

This paper presents two compact slot array antennas for the 79 GHz automotive band integrated into a 28 um thick benzocyclobutene (BCB) substrate attached to a 325 um thick 5–20 Ωcm bulk resistivity silicon wafer. The two antennas are a transmit (TX) 1×8 slot array antenna with a size of 1×23 mm and a receive (RX) 8×8 slot array antenna with a size of 15×23 mm. Promising performance has been measured with the TX and RX sub-array antennas (gain >4 dBi) with good matching to 50 Ω (RL>10 dB) in the frequency range 70–90 GHz. By using a metal cavity, mounted on the back of the antenna, parallel plate modes could be reduced and the gain could also be increased by 2dB. The measured and the simulated results are consistent.
