Electrical Performance Analysis of Broadband Dipole Antenna under Wind Load

The complex weather environment has a significant effect on the structural deformation and electrical performance of the broadband dipole antenna. In this paper, an electromechanical coupling analysis method is proposed to analyze the nonlinear response of the Broadband dipole antenna under multi-wind wind load, and the structural analysis of the broadband dipole antenna under wind load is carried out by the nonlinear finite element method, and the electrical performance analysis of the antenna is carried out by the method of moments based on the geometric model of the deformed broadband dipole antenna. The impedance characteristics and pattern of the antenna are calculated under wind load. The calculation results show that the import impedance of the antenna is almost the same, whether the antenna with multi-wind wind load or not. When the antenna is loaded with wind, the antenna pattern has little effect on the low-frequency band and a larger impact on the high-frequency band. The results of this paper provide a basis for the selection and design of the antenna, and the analysis method in this paper has certain reference significance for the same type of antenna.
