Abstract

The invention discloses a compact type dual polarization micro base station antenna with high isolation. The compact type dual polarization micro base station antenna comprises a floor substrate, a feed substrate I, a feed substrate II, an antenna substrate and a metal wall, wherein a square structure consisting of the metal wall is arranged on the upper surface of the floor substrate; the feed substrate I and the feed substrate II are arranged inside the square structure consisting of the metal wall and are vertical to the floor substrate; the antenna substrate is arranged above the feed substrate I and the feed substrate II; a patch antenna is arranged on the lower surface of the antenna substrate; the diagonal line of the patch antenna coincides with the positions of the feed substrate I and the feed substrate II which are orthogonally placed; and grooves symmetrical in size are formed in two corners of the patch antenna in the diagonal direction right above the feed substrate II. The dual polarization micro base station antenna disclosed by the invention is compact in structure and low in manufacturing cost, and can meet the application in various environments; and compared with other micro base station microstrip antennas, the dual polarization micro base station antenna has good directed radiation characteristic and stable directional diagram characteristic.

Description

technical field [0001] The invention relates to the technical field of base station antennas, in particular to a compact dual-polarization micro base station antenna with high isolation. Background technique [0002] As the ratio of mobile data services to the total amount of telecom services is increasing, especially in public places such as schools, shopping malls, office buildings, and conference centers; in addition, some urban villages and suburban areas have blind spots in signal coverage. If the network capacity is directly increased by building a macro base station, the cost is very high, including site selection, equipment procurement, installation, commissioning and maintenance will consume a lot of manpower, financial resources, material resources and time. Therefore, it is an unwise choice to simply use the macro cellular network to take into account the coverage of the area. It is precisely because of the above challenges that the industry proposes to use small...
