Optimization of 2.45-GHz pixel rectenna for wireless power transmission using mixed integer linear programming

In this paper we provide a 2.45-GHz pixel rectenna design for wireless power transmission. We propose a deterministic optimization method called Mixed Integer Linear Programming (MILP) to optimize the pixel antenna. The global optimal hardwire of the pixel antenna is simulated, fabricated, and measured. An optimized 2.45-GHz rectifier is also proposed and simulated in this paper.
