Abstract

The invention relates to a dual-frequency dual-polarized antenna and a radiating unit. The radiating unit comprises two pairs of radiating arms which are arranged in an orthogonal polarization way anda balun used for feed to the radiating arms. A cross hollow area is formed between the two pairs of radiating arms. In the above-mentioned radiating unit, one pair of radiating arms is equivalent toa dual-frequency +45-degree polarized half-wave array, and the other pair of radiating arms is equivalent to a dual-frequency -45-degree polarized half-wave array, and the whole body form a dual-frequency dual-polarized radiating unit. Because the arm surface area of the high-frequency radiating arm is smaller than that of the low-frequency radiating arm, the distance between the side edge of thehigh-frequency radiating arm back to the center of the cross hollow area and the center of the cross hollow area is smaller than the distance between the side edge of the low-frequency radiation arm back to the center of the cross hollow area and the center of the cross hollow area, the plane beam symmetry and the cross polarization ratio of the antenna can be well improved, and the distance between the subarrays is relatively increased, so that the effect of improving the coupling degree between the subarrays is achieved, and the user experience effect is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a dual-frequency dual-polarization antenna and a radiation unit. Background technique [0002] The operating frequency of the 5G network is higher than that of the traditional 4G network, and the base station antenna of the 5G network needs to meet the requirements of dual-band work at the same time. The development of the radiation unit for dual-band work has become a necessary means to achieve its goal. However, in order to meet the requirements of dual-frequency operation, the coupling between sub-arrays is poor in the case of the traditional dual-frequency dual-polarized antenna with the same volume size. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art and provide a dual-frequency dual-polarization antenna and a radiation unit, which can satisfy the dual-frequency operating characteristics and improve t...
