Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0038] It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be pres...

Abstract

The invention discloses a base station, a broadband dual-polarization filtering magnetoelectric dipole antenna and a radiation unit thereof. The radiation structure includes two groups of dipoles whose polarization directions are orthogonal to each other, and each group of dipoles includes two oppositely arranged dipoles. The radiator; the balun structure includes four groups of balun components, each group of balun components includes two relatively spaced baluns, and relatively spaced and electrically connected feeders and open-circuit branches, one of which is a balun It is electrically connected to one radiator, and the other balun is electrically connected to another adjacent radiator, the feeder is arranged at a distance from one of the baluns, and the open branch is arranged at a distance from the other balun, and The balun is set between the feeder and the open stub. There will be no mutual coupling between the radiating elements; thus, the performance of the broadband dual-polarization filtering magnetoelectric dipole antenna adopting the radiation element is good; thus, the base station adopting the broadband dual-polarization filtering magnetoelectric dipole antenna The overall performance is good.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a base station, a broadband dual-polarization filtering magnetoelectric dipole antenna and a radiation unit thereof. Background technique [0002] With the rapid development of wireless communication technology, the broadband dual-polarization filter magnetoelectric dipole antenna (hereinafter referred to as the magnetoelectric dipole antenna) has the advantages of wide bandwidth, high directivity, low cross polarization, and low back lobe radiation. It has a good application prospect. In the application process of the traditional magnetoelectric dipole antenna in the multi-band base station array, in order to meet the miniaturization requirements of the base station, the radiating elements of different working frequency bands are usually spaced close together, resulting in strong mutual coupling, so that the magnetoelectric dipole The overall performance of the a...
