Abstract
Beamforming algorithms have been applied to millimeter wave joint communication and sensing systems. Applying weight-beamforming algorithms to the transmit and receive beams can reduce the self-interference of the system while maintaining the integrity of the beam. Considering that there are still some limitations of beamforming algorithms in JCAS systems, this paper proposes a design method for antenna arrays applied to JCAS systems from the perspective of antenna array layout, which can directly reduce the coupling between transmit and receive antenna arrays. The results show that the designed antenna array layout can enhance the decoupling between the antenna arrays, thus reducing the system self-interference.
