Abstract
The invention relates to a dual-polarization near-field measurement probe, which includes a first antenna unit, a second antenna unit and a metal spacer; the first antenna unit and the second antenna unit both include: a dielectric substrate; There are index slots and transition slots, the index slots and transition slots are set in the middle of the radiation unit, the index slots communicate with the transition slots; the feed unit, the feed unit is set on the second board; metal vias, metal The via hole runs through the dielectric substrate and electrically connects the radiation unit and the feed unit; the first antenna unit and the second antenna unit are engaged and connected; the metal spacer is set on the second On the board, and the metal spacer is between the feed unit of the first antenna unit and the feed unit of the second antenna unit, the present invention improves the problem of excessive cross-polarization level of the traditional probe due to the introduction of the metal spacer , At the same time, it also improves the problem of poor isolation of traditional probes.
Description
technical field [0001] The invention relates to the technical field of near-field measurement, in particular to a dual-polarized near-field measurement probe. Background technique [0002] With the rapid development of aerospace and electronic communication technology, the performance requirements for various radar and communication systems are also getting higher and higher. Antenna is one of the key components of radio systems such as radar and communication, and its performance is directly related to the performance of the entire system. Antenna measurement technology, including far-field and near-field measurement, is playing an increasingly important role in modern antenna technology and military scientific research. [0003] Near-field measurement technology is not only regarded as an effective method for measuring antenna performance in developed countries, but also an essential means for researching new antennas, and has great potential to penetrate into other field...
