【摘要】：針對(duì)甚低頻發(fā)射天線輸入電抗高、輸入電阻小而導(dǎo)致的天線Q值高、帶寬窄、輸入功率受限、天線系統(tǒng)效率低等問(wèn)題,研究了傘型和T型甚低頻發(fā)射天線的頂負(fù)載在不同電氣連接方式下的天線輸入阻抗,提出在不改變天線總體結(jié)構(gòu)的情況下,改變頂負(fù)載電氣連接方式可優(yōu)化天線的輸入阻抗的方法.計(jì)算結(jié)果和理論分析均表明,優(yōu)化后的天線頂負(fù)載連接方式可降低甚低頻發(fā)射天線的輸入容抗、提高天線的輸入電阻,從而可提高天線系統(tǒng)效率和功率容量、增加天線帶寬,對(duì)改善甚低頻發(fā)射天線性能和提高天線電氣工作安全性具有重要意義.
[Abstract]:Aiming at the problems of high input reactance, low input resistance, high Q value, narrow band width, limited input power, low efficiency of antenna system, etc. The input impedance of the top load of the Umbrella and T-type VLF transmitting antennas under different electrical connection modes is studied. It is proposed that the antenna structure should not be changed. The input impedance of the antenna can be optimized by changing the electrical connection mode of the top load. The results of calculation and theoretical analysis show that the optimized connection mode of the top load of the antenna can reduce the input capacitance reactance of the very low frequency transmitting antenna and increase the input resistance of the antenna. Therefore, it can improve the efficiency and power capacity of antenna system, increase the bandwidth of antenna, improve the performance of very low frequency transmitting antenna and improve the safety of antenna electrical operation.
