Wide-angle Impedance Matching of Antenna Arrays with Circuit Synthesis and Optimization Tools

Future 5G wireless communication requires beam steerable antenna arrays. The challenge of these antenna arrays is the changing input impedance as a function of steering angle, which is difficult to compensate with matching networks. We propose a novel method of designing and matching antenna arrays at different steering angles simultaneously with the combined usage of unit cell model and Optenni Lab software aimed for matching circuit synthesis and optimization. We apply the method to a linear patch antenna array. The results show the potential of this approach.
