Abstract [en]

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 Omega cm bulk resistivity silicon wafer. The two antennas are a transmit (TX) 1x8 slot array antenna with a size of 1x23 mm and a receive (RX) M slot array antenna with a size of 15x23 mm. Promising performance has been measured with the TX and RX sub-array antennas (gain >4 dBi) with good matching to 50 11 (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.
