- A Concept of PIM Frequency Generated Array for Radiating Nonlinear Beam Steering Chenyu Liu Xiong Chen Yanyan Tian Ming Yu Microwave and Optical Technology Letters ABSTRACT This letter introduces a concept of Passive Intermodulation Frequency Generated Array(PFGA), which is a novel design based on microstrip patch array which incorporates passive intermodulation (PIM) as an excitation source. By adjusting the magnitudes and phases of PIM fed into the four antenna ports, direction steering of the nonlinear beam propagation, can be achieved at PIM frequency. This PFGA design proves the possibility of independent controlling and synthesis of PIM as port sources to achieve overall PIM beam shifting. Within a specific voltage range, the PIM power distribution angle can be independently adjusted, while the control channels of the PIM beam are independent of the linear beam. This PIM beam steering phenomenon preliminarily proves that nonlinear frequency signal can serve as an independent communication channel for transmitting additional information without interfering with the main frequency signal. It also demonstrates that PIM beam can propagate in different directions, thus enhance the freedom of PIM communication. Simulations and experimental results are in good agreement, verifying the feasibility of the PFGA concept. This innovative PIM communication method is expected to enhance the utilization of nonlinear effects, providing new sights for areas like radiation PIM standards establishment, nonlinear optimization of MIMO multi‐channel systems, and channel capacity expansion. 10.1002/mop.70593 http://onlinelibrary.wiley.com/termsAndConditions#vor
