“…e ground loss resistance of a VLF thirteen-tower umbrella antenna can be split into H-field loss resistance and E-field loss resistance [5,19,20]. Because the antenna structure is extremely complex, it is very difficult to accurately solve its ground loss resistance by analytical calculation [21]. In this study, the combination of numerical simulation and analytical calculation is used to solve its ground loss resistance.…”

The concept of multituned thirteen-tower umbrella antenna is developed in this study to address the problem that increasing the power capacity of a single-tuned VLF transmitting antenna leads to a decrease in self-resonance. The calculation method of electrical parameters such as input resistance and radiation efficiency is theoretically analyzed based on the radiation resistance of different antenna units in a thirteen-tower umbrella antenna, and the electrical performance of the single-tuned and multituned thirteen-tower umbrella antennas is simulated and compared with the measured results of the Cutler antenna. Under the same antenna structure parameters and input power, the antenna radiation efficiency of the multituned thirteen-tower umbrella antenna is basically the same as that of the single tuned one. However, the multituned antenna has lower input current and higher self-resonance, which can effectively improve the antenna’s safety and broaden its operating frequency range.
