摘要

Trailing Wire Antenna on aircraft is used to transmit VLF/LF messages to submarines. It has two types including Single Trailing Wire Antenna(STWA) and Dual Trailing Wire Antenna(DTWA). STWA is a long wire which is half of wavelength; DTWA consists of a short wire and a long wire, and the total length of DTWA is half of wavelength. Both of two antennas are about more than 5000 meters. This paper presents a method of establishing such large models of airborne VLF single/dual trailing antenna systems. Then discuss and compare two antennas' different EM radiation characteristics and impedances based on simulation results. The results of the calculations suggest that the performance of DTWA is better than STWA. And DTWA is more suitable to carry high-power transmitter and transmit messages to a long distance.
