FIELD: electricity.
SUBSTANCE: antenna assembly mounted at the device of control and diagnostics in power supply line comprises a load-bearing part made of insulating dielectric material with the preset thickness and curved shape of outer and inner surface, antenna radiator shaped as curved surface along the outer surface of the load-bearing part, earthing element shaped as curved surface along the outer surface of the load-bearing part and exciting part passing through the load-bearing part for electrical connection of the antenna radiator and earthing element. The antenna assembly is mounted at one side of the device to control and diagnose the power supply line in direction of the power supply line when the device of control and diagnostics is mounted in the power supply line.
EFFECT: reduced interference, high amplification factor, efficiency factor, potential miniaturisation, minimisation of temperature impact and increased service life.
