棒形天線耦合雷電電磁波及抑制方法
[Abstract]:Aiming at the problem of coupling the lightning electromagnetic wave signal with the rod-shaped antenna, using the method of combining the experiment and the theory, a rod-shaped antenna is established to receive the equivalent circuit of the lightning electromagnetic wave signal, the frequency spectrum and the energy distribution rule of the lightning electromagnetic wave signal are analyzed, A method of using transient voltage supply (TVS) to suppress the energy of a rod-shaped antenna coupled with lightning electromagnetic wave is proposed. The experiment shows that the center frequency and the bandwidth of the antenna are slightly smaller from the curve of the rod-shaped antenna S11 after the power feeding terminal is connected in parallel with the TVS tube, the parallel TVS tube of the feeding end can effectively inhibit the amplitude of the coupling lightning electromagnetic wave voltage of the rod-shaped antenna, and the two different types of TVS tubes are connected in parallel at the feeding end, The amplitude of the coupling lightning electromagnetic wave voltage of the rod-shaped antenna can be suppressed to be within the range of 6.8 V to 7 V, respectively. The experimental results and the theoretical analysis conclusions are in good agreement. The results of the study are of great significance to the suppression of the coupling of the rod-shaped antenna with the energy of the lightning electromagnetic wave.
