A 5g ultra-wideband antenna unit and a 5g ultra-wideband dual-polarized antenna

Abstract

The invention discloses a 5G ultra-wideband antenna unit and a 5G ultra-wideband dual-polarized antenna. A 5G ultra-broadband antenna unit includes: a dielectric plate and flag-shaped oscillators formed on both sides of the dielectric plate and mirrored with each other; each flag-shaped oscillator is divided by at least two 1 / 4λ oscillator lengths with different 5G frequencies The coplanar design is formed, and λ is the wavelength corresponding to the 5G frequency; each flag-shaped vibrator is tilted relative to the central axis of the dielectric plate, so that the electrical length of the vibrator arms of the flag-shaped vibrators on both sides is gradually transformed from the initial frequency of the antenna unit to the antenna unit stop frequency. The present invention not only satisfies the network communication frequency bands of 2G and 4G network standards, but also satisfies the frequency band use requirements of 5G network standards through frequency division co-planar flag-shaped vibrator technology and V-shaped frequency balance slot technology, while abandoning conventional filters Combined circuit has the advantages of less material, miniaturization, ultra-broadband, low cost, simple structure and easy mass procurement and manufacturing.

Description

technical field [0001] The present invention relates to the field of antenna technology, in particular to a 5G ultra-wideband antenna unit and a 5G ultra-wideband dual-polarized antenna. Background technique [0002] With the official issuance of 5G licenses by the Ministry of Industry and Information Technology in 2019, China's mobile communication network system has officially entered the 5G era, and the construction of domestic 5G communication networks is in full swing. Ushered in a blowout performance outbreak. [0003] Since the beginning of the 21st century, China's demographic dividend has gradually faded, and labor costs have increased year by year. Therefore, many companies have added a lot of mechanized equipment to replace labor to offset the rise in labor costs. With the entry of more and more competitors in the antenna industry, the low-price competition is gradually becoming fiercer. Based on this, antenna practitioners must develop more cost-effective produ...

Problems solved by technology

like figure 1 As shown, the conventional dual-frequency dual-polarization antenna unit scheme on the market is basically to design two single-frequency dual-polarization antenna units (low-frequency oscillator 1' and high-frequency oscillator 2'), and then combine them through the filter 3' , but this design method is complex, with many materials, many processes, high assembly labor costs, high overall costs, low production efficiency, and multi-section assembly is likely to cause a lot of instability and uncertainty in the third-order intermodulation index of the antenna. Specifically, due to the large number of vibrators and many parts in the conventional design scheme, there are more connection feed points between the cable and each component, and the more installed parts means that the probability of problems between the parts will be greater , Such as vibrator virtual soldering, missing soldering, solder short circuit, too much or too little solder, screws not tightened, screws too tight beyond the torque limit, vibrator installation skew and other factors will have a great impact on the performance of the antenna
