Abstract

The invention discloses a dipole antenna for a broadband base station and a base station antenna. The dipole antenna for a broadband base station comprises a substrate and two pairs of dipole antennaunits at an angle of 90 degrees, each pair of the dipole antenna units comprises two dipole antenna subunits that are coupled by a connector for feeding. The dipole antenna subunit comprises an outerring and an inner ring that is located in the outer ring and connected to the outer ring. The dipole antenna for a broadband base station and the base station antenna provided by the invention have advantages of wide coverage of frequency band, excellent performance, planarization, multi-mode resonance and gain stability, as well as simple structure, convenient manufacture and low production cost.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband base station dipole antenna and a base station antenna. Background technique [0002] With the rapid development of wireless communication technology, the application of dual-polarized antennas is becoming more and more extensive. In terms of reducing multi-channel attenuation and increasing channel capacity of the base station, the application of ±45° dual-polarized antennas is particularly important. [0003] In order to meet the requirements of 2G, 3G, and 4G communication systems at the same time, the dipole antenna of the base station needs to cover the 1710-2690MHz frequency band. With the diversification of base station application scenarios, the requirements for the structural section of the antenna element of the base station are getting higher and higher in many occasions. Therefore, how to design a planar element antenna is a challenge to be faced in the ...
