2.6 Antenna
The BoosterPack includes onboard-etched antennas for the four receivers and two transmitters that
enable tracking multiple objects with their distance and angle information. This antenna design enables
estimation of distance and elevation angle that enables object detection in a two-dimensional plane.
Figure 10 shows the PCB antennas.
Figure 10. RX and TX Antennas
The antenna peak gain is > 9 dBi across the operating frequency band of 76 to 81 GHz. The peak output
power with the antenna gain is < 55 dBm EIRP, as required by the European regulations. The radiation
pattern of the antenna in the horizontal plane (H-plane Phi = 0 degrees) and elevation plane (E-plane Phi
= 90 degrees) is shown by
Figure 10 .
