Problems solved by technology

In the prior art, the height of the vibrator unit is generally greater than or equal to a quarter of the central working wavelength, which is conducive to the matching of the vibrator and the balance of the balun, but there are the following problems: due to the height limit of the vibrator itself, it is difficult to reduce the thickness of the antenna Realize the miniaturization of the antenna; the problem of poor cross-polarization of the vibrator itself requires adding a boundary next to the vibrator to achieve good cross-polarization, which increases the cost

Abstract

The present invention relates to a low profile ultra wideband dual polarization high frequency oscillator unit. The low profile ultra wideband dual polarization high frequency oscillator unit comprises an oscillator, and a substrate plate and a cover plate which are connected with the two ends of the oscillator respectively. The high frequency oscillator unit works in a frequency band range of 1695-2690 MHz, the height of the oscillator is less than 0.2 times of a central operating wavelength, namely, the distance between the cover plate and the substrate plate is less than 0.2 times of the central operating wavelength, thereby effectively increasing the bandwidth of an antenna, simplifying the boundary of a wideband dual polarized antenna high frequency unit, and reducing the thickness of the antenna. The low profile ultra wideband dual polarization high frequency oscillator unit is simple in structure, is easy to manufacture, is suitable for the volume production, and has the advantages of small appearance size and low cost.

Description

technical field [0001] The invention relates to the technical field of antennas, and more specifically relates to a low-profile ultra-broadband dual-polarized high-frequency dipole unit. Background technique [0002] With the rapid development of mobile communication technology and the shortage of antenna resources on the base station, the base station antenna is not only required to have good broadband and high radiation performance, but also needs to be miniaturized. The vibrator unit is an important part in the antenna of the mobile communication base station system. Its quality directly affects the overall performance of the antenna, and its size also affects the overall size of the antenna. In the prior art, the height of the vibrator unit is generally greater than or equal to a quarter of the central working wavelength, which is conducive to the matching of the vibrator and the balance of the balun, but there are the following problems: due to the height limit of the v...
