Abstract

The invention discloses a broadband miniaturized Vivaldi antenna for discharge detection, and relates to the technical field of antennas. The antenna comprises a first radiation patch antenna and a second radiation patch antenna. The first radiation patch antenna is provided with a first gradual change gap. The second radiation patch antenna is provided with a second gradual change gap. The first radiation patch antenna and the second radiation patch antenna have the same structure, are symmetrically arranged on the front surface of the dielectric plate, and are electrically connected through the first loading resistor. According to the Vivaldi antenna, the structure is effectively improved, the Vivaldi antenna has the advantages of being wide in frequency band, small in size, simple in structure and low in manufacturing cost, and the dielectric lens is further arranged, so that the radiation performance of the antenna in the wide frequency band is more stable. The invention provides a comprehensive thought for designing a broadband, miniaturized and high-gain antenna.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband miniaturized Vivaldi antenna for discharge detection. Background technique [0002] The non-positive discharge of high-voltage electrical equipment seriously threatens the driving safety of high-speed EMUs. As a sensor for discharge detection technology based on space electromagnetic radiation signals, the main requirements for the antenna are miniaturization, broadband and high gain. At present, there have been some studies on antenna sensors in this field at home and abroad, but they still cannot meet the performance requirements of miniaturization, broadband and high gain at the same time. [0003] Antenna sensors used to detect low-frequency space electromagnetic radiation signals mainly include biconical antennas and logarithmic periodic antennas. However, such detection antennas are large in size and are not suitable for installation on the car body of high-sp...
