The invention relates to the antenna field, in particular to a multi-band dual-polarized antenna oscillator and an antenna system thereof. The multi-band dual-polarized antenna oscillator comprises a reflecting plate, a low-frequency radiation fin and a high-frequency medium plate which are sequentially arranged in parallel from bottom to top, the middle of the reflecting plate is provided with a through hole in which a low-frequency medium plate is embedded; a low-frequency shielding box is mounted below the low-frequency medium plate, the low-frequency shielding box, the reflecting plate embedded with the embedded low-frequency medium plate and the low-frequency radiation fin are connected in series through a first fixing column; and the low-frequency radiation fin and the high-frequency medium plate are fixedly connected through a bearing seat. In the multi-band dual-polarized antenna oscillator and the antenna system which are provided by the invention, a first radiation structure, a second radiation structure, a third radiation structure and a fourth radiation structure on the high-frequency medium plate are adopted by the multi-band dual-polarized antenna oscillator to be used as the guiding fins of a fifth radiation structure on the low-frequency radiation medium plate so as to greatly lower the height, save space and have simple structure, higher gain and favorable cross-polarization characteristic.
Description
technical field [0001] The invention belongs to the field of antennas, and in particular relates to a multi-frequency dual-polarization antenna element and an antenna system thereof. Background technique [0002] With the development of mobile communication technology, the requirements for base station antennas are getting higher and higher, especially due to the shortage of space resources, there are stricter requirements for the size and weight of antennas. At present, the structure of common multi-frequency polarized antenna elements is relatively complex, high in height, and takes up a large space. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a multi-frequency dual-polarized antenna element, aiming at solving the problems of the conventional multi-frequency polarized antenna element in the prior art that the structure is relatively complex, the height is high, and the space occupied is large. [0004] The emb...
