Analysis of Radiation Characteristics of Compressed V-shape Dipole Antenna

Abstract

In order to solve the problem of blind radiation spot of the traditional whip antenna mounted on the surface unmanned boats, a compressed V-shape dipole antenna is designed, which is omnidirectional and has a larger directivity especially when the hull is tilted. Calculated the radiation field strength of the compressed V-shape dipole antenna when it is tilted in various directions; The electrical characteristics of the compressed V-shape dipole antenna were obtained using FEKO electromagnetic simulation software, and the far-field experimental measurement and comparison experiment with the traditional whip antenna and the standard V-shape dipole antenna were carried out. Theoretical calculations, simulations, and experiments all show that the compressed V-shape dipole antenna has better directivity when interfered by the flowing sea surface, and the results are consistent, avoiding the problem of blind working spots, and the radiation process is stable and reliable.
