A method for tailoring the antenna harmonic emission limit of radio frequency equipment based on quantitative calculation

In order to realize the electromagnetic compatibility in the system, a method based on electromagnetic compatibility analysis is proposed to solve the problem of tailoring the antenna harmonic emission limits in the relevant standards. Based on the analysis for the influence factors of the limit, the model of interference contribution level and limit constraint level is proposed, then the matrix of interference contribution level and limit constraint level is established. The feasibility of the method is verified by taking a simulation system into account. The tailored suggestions for the transmiting antenna in the system are 74dB, 77dB and 93dB respectively, and the tailored suggestion for the whole system is 93dB, indicating that the method is feasible. This method can be applied to complex systems and provide reference for the design of antenna harmonic interference suppression.
