Abstract

The invention relates to a mobile communication antenna technology, particularly to a wideband dual-polarization radiating unit. The wideband dual-polarization radiating unit includes an annular pedestal, feed balund arranged on the annular pedestal, dipoles arranged on the feed baluns, and coupling structures coupling two adjacent radiating arms of two adjacent dipoles. The structure of coupling the radiating arms of two dipoles through coupling sheets lengthens resonance length of the radiating arms in disguised form, thereby reducing the size of the whole dipole, and effectively broadening bandwidth of the radiating unit. The invention also relates to a base station antenna that applies the abovementioned radiating unit.

Description

【Technical field】 [0001] The invention relates to a mobile communication antenna technology, in particular to a broadband dual-polarization radiation unit and a base station antenna. 【Background technique】 [0002] With the gradual acceleration of the construction of the fourth-generation mobile communication network, various operators began to seek downward compatibility with 2G and 3G standards such as GSM800, GSM900, DCS1800, PCS, CDMA1800, and CDMA2000, as well as upward compatibility with 4G standards such as LTE700 and LTE2600. Ultra-wideband antennas, the demand for broadband antennas for base stations is increasing. [0003] However, as the frequency band widens, the size of the antenna increases accordingly, which causes inconvenience in installation and is not conducive to the miniaturization of the antenna. Therefore, it is an inevitable trend to design a radiating unit that is small in size and compact in structure while having a wider frequency band. 【Content...
