The invention relates to a radar antenna for a vehicle bumper panel. For example, a system may include: a radome to be attached to a vehicle bumper panel; an antenna array on a printed circuit board (PCB), the antenna array between the PCB and the radome, the antenna array including a transmit (Tx) antenna configured to transmit Tx radar signals via the radome and the vehicle bumper panel, and a receive (Rx) antenna configured to receive Rx radar signals based on the Tx radar signals; and an absorption spacer located in a spacer region between the PCB and the radome, the spacer region separating the Tx antenna from the Rx antenna, the absorption spacer configured to absorb a reflected signal formed by reflection of the Tx radar signal from the vehicle bumper panel.
本发明涉及用于交通工具保险杠面板的雷达天线。例如,系统可包括:要附接到交通工具保险杠面板的雷达罩;印刷电路板(PCB)上的天线阵列,该天线阵列处于PCB与雷达罩之间,该天线阵列包括发射(Tx)天线以及接收(Rx)天线,该发射(Tx)天线被配置成用于经由雷达罩和交通工具保险杠面板发射Tx雷达信号,该接收(Rx)天线被配置成用于基于Tx雷达信号来接收Rx雷达信号;以及吸收间隔件,该吸收间隔件位于PCB与雷达罩之间的间隔件区域中,该间隔件区域将Tx天线与Rx天线分开,该吸收间隔件被配置成用于吸收由Tx雷达信号从交通工具保险杠面板的反射形成的经反射的信号。
