Problems solved by technology

However, in the nesting scheme of high and low frequencies, the mutual influence between high and low frequencies is great, resulting in the front-to-back ratio in the radiation direction, the cross-polarization ratio, and the isolation can not meet the expected standards
[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention provides a multi-frequency ultra-wideband oscillator and an antenna. The multi-frequency ultra-wideband oscillator comprises a low-frequency oscillator, a reflecting plate, a first high-frequency oscillator and two coupling feed sheets. The low-frequency oscillator comprises a plurality of radiation arms, a plurality of support arms and a base, the tops of the support arms are connected with the radiation arms, and the bottoms of the support arms are connected with the base. The radiation arms, the support arms and the base form a mounting cavity together. Each radiation arm is provided with vertically downward bending parts on the two sides respectively. The reflecting plate is fixed on the base. The first high-frequency oscillator is nested in the mounting cavity of the low-frequency oscillator, and the first high-frequency oscillator is fixed on the reflecting plate. The two coupling feed sheets are orthogonally connected and are arranged between the reflecting plate and the base. Therefore, the multi-frequency ultra-wideband oscillator provided by the invention has the effects of high front-to-back ratio, high cross polarization ratio, high isolation and ultra-wideband in the radiation direction.

Description

technical field [0001] The invention relates to the technical field of antennas in mobile communication base stations, in particular to a multi-frequency ultra-wideband dipole and an antenna. Background technique [0002] With the development of mobile communications, the miniaturization and multi-frequency of base station antennas have become an important trend in the development of antennas. At present, the high and low frequency nesting scheme is an important method to realize multi-frequency antenna elements, and it is more and more widely used in antenna layout. However, in the high and low frequency nesting scheme, the high and low frequencies have a great influence on each other, resulting in the front-to-back ratio in the radiation direction, the cross-polarization ratio, and the isolation can not meet the expected standards. [0003] In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it. Co...
