Design of Airborne VLF Dual Trailing Wire Antenna

The airborne Dual Trailing Wire Antenna (DTWA) has a complex shape that makes it challenging to calculate using the conventional analytical method and challenging to obtain results with high precision. The purpose of this thesis is to study the performance of the Dual Trailing Wire Antenna on the aircraft. The operation theory of the airborne DTWA is presented in this paper along with a method of establishing such large models of airborne Very Low Frequency (VLF) dual trailing wire antenna systems. The performance of the DTWA model is calculated, which is 6000 meters long. Then discuss dual trailing wire antenna’s EM radiation characteristics and impedances by the analysis of simulation results. The electromagnetic field distribution and induced current of the Airborne Dual Trailing Wire Antenna are analyzed by calculating the radiation field of the DTWA. The conclusions are beneficial for further study on the application of airborne VLF communication systems.
