  1. How did you simulate with MATLAB? What kinds of simulations did you conduct? EM simulation or use the far-field/near-field equations of general phase array beamforming?
  2. Will the PA in Figure2 induce additional phase shift? How will you manage this problem?
  3. How do you implement setups in Figure 5 and Figure 6? Still in MATLAB?

Thank you for your comment.

Simulation is conducted with the MATLAB Simulink, which enables the model to be simulated in configurable timesteps.

Currently, there are two models, one using the far-field equation of phased-array beamforming to calculate the array factor of a given configuration, as suggested in Figure 5. The other one is calculated otherwise, it takes the small distance differences between antenna patch elements into the calculation, they lead to phase shifting at the receiving side, with the phase shifter induce additional phase shift, the waves from antenna elements form constructively or destructively in space, it gives the beamforming characteristics as a result.

Currently, the model only focuses on the system-level simulation, however, the additional phase shift in any component can also be added to the setting.
The setups in Figures 5 and 6 are implemented in MATLAB Simulink.
