Problems solved by technology

[0002] In order to deal with electronic targets such as swarm drones, the best solution is to use ultra-wideband electromagnetic waves, but the current ultra-wideband electromagnetic wave antennas generally have low power or high power The bandwidth is narrow, and the pressure resistance is particularly critical. The conventional ultra-wideband antenna is only used for communication and radar equipment. As a damage strike weapon, its operating distance is a relatively important indicator. It is extremely important to solve the problem of antenna withstand voltage while broadbanding. At present, in the case of high-power and ultra-wideband antennas, the voltage between the plates of the conventional design reaches 1 million volts, which is prone to fire and burn the antenna. The bandwidth is not enough, and the transmission The problem of limited efficiency

Abstract

The invention relates to the technical field of radiation antennas, and provides a high-power ultra-wideband electromagnetic radiation antenna. The objective of the invention is to solve the technical problem that an antenna is easy to burn after the radiation factor of the antenna reaches more than 1MV. According to the main scheme, the device comprises an impedance transformer (1) and an index involute antenna (A) connected with the impedance transformer (1), the index involute antenna is sleeved with an outer cover (4), and transformer oil used for immersing the index involute antenna (A) is arranged in the outer cover (4). According to the invention, the high voltage of 1 million volts can be formed between the polar plates when the device works at the power capacity of 1 MV, and the polar plates are easy to ionize to form sparks to burn the device, so that the top ends of the polar plates are of an inward rolling structure to prevent the device from being burnt.

Description

technical field [0001] The invention relates to the technical field of radiation antennas, and provides a high-power ultra-wideband electromagnetic radiation antenna. Background technique [0002] In order to deal with electronic targets such as swarm drones, the best solution is to use ultra-wideband electromagnetic waves. However, current ultra-wideband electromagnetic wave antennas generally have low power or narrow bandwidth when the power is high. Among them, withstand voltage is particularly critical. Conventional ultra-wideband antennas are only Used in communication and radar equipment, as a damage strike weapon, its operating distance is a relatively important indicator, which is reflected in the withstand voltage of the antenna. It is extremely important to solve the problem of antenna withstand voltage while ensuring ultra-wideband. At present In the case of high-power and ultra-broadband antennas, the voltage between the conventionally designed plates reaches 1 m...
