Abstract
The present application discloses embodiments that relate to a radar system. The embodiments may include a plurality of radiating waveguides each having a waveguide input. The embodiments also include an attenuation component, which can be located on a circuit board. The embodiments further include a beamforming network. The beamforming network includes a beamforming network input. The beamforming network also includes a plurality of beamforming network outputs, where each beamforming network output is coupled to one of the waveguide inputs. Additionally, the beamforming network includes an attenuation port, wherein the attenuation port is configured to couple the beamforming network to the attenuation component. The attenuation component dissipates received electromagnetic energy.
