|1. (WO2017035726) ANTENNA OSCILLATORS FOR DUAL-POLARIZATION OF MULTIBAND ANTENNA|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||ANTENNA OSCILLATORS FOR DUAL-POLARIZATION OF MULTIBAND ANTENNA|
Antenna oscillators (101, 102) for dual-polarization of a multiband antenna comprise: four radiating elements (201), a balun element for feeding power to the radiating elements (201), and a fixing board (202) for fixing the balun element. The balun element comprises two dielectric plates (203). Two signal transmission elements (301), one power-feeding element (401) and two filtering elements (402) are printed on each of the dielectric plates (203). By configuring the filtering element (402) into an LC resonant tank structure and adjusting the filtering element (402) to realize decoupling in a certain band, even if the antenna oscillators (101, 102) are applied to a scenario in which oscillators of different bands operate cooperatively, the radiating elements (201) will not generate a strong electromagnetic coupling effect over different frequency bands when closely arranged. Therefore, the antenna oscillators (101, 102) ensure that an antenna can function normally in related frequency bands.
