More Information
Summary:The invention belongs to the technical field of RFID reader-writers, and particularly discloses a dispersed RFID reader-writer planar antenna and a design method and application thereof, and the method comprises the steps: constructing an optimization objective function and constraint conditions of a structure parameter variable R of the dispersed RFID reader-writer planar antenna, the ratio of the magnetic field current ratio coefficient of the objective function to the internal resistance of the planar antenna of the RFID reader-writer is optimized, and the parameter R = (r1, r2,... rN) is a vector set of the radiuses of N circular rings of the antenna; and solving the optimized objective function by adopting a Lagrangian multiplier method, directly performing parameter scanning on the parameter N, constructing N + 1 equations to solve local optimal solutions of the parameter R under different parameters N, further determining a global optimal solution from the local optimal solutions, and completing the de
