Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation examples, but it is not intended to limit the technical solution of the present invention.

[0033] image 3 It is a schematic diagram of the structure of the preset two-array antenna sliding device of the present invention. The upper and lower sliding devices 01a, 01b, 01a', 01b' and the support frame 02, 02' are connected together by the pole 03. Before the antenna is not installed, first Make sure that the support frames 02 and 02' are horizontal and on the same vertical plane, then adjust the distance between the two sets of sliding devices according to the requirements, and then use the fixing bolts 14 and 14' to fix the sliding devices on the support frames 02 and 02', and finally The antenna upper and lower installation components are correspondingly installed on the sliding pole 11 on the up and down sliding device. When the ...

Abstract

The invention discloses a multi-input multi-output antenna with an adjustable separation distance, which comprises a pole, a support and at least two array antennas, wherein the support is perpendicular to the pole; the two array antennas are arranged on the support vertically and can be installed on the support in a mode of sliding along the support, and the antennas can be remotely adjusted through an electronic control device and a motor. The invention has the advantages of relatively simple structure, easy realization, strong field operability and the like.

Description

[technical field] [0001] The invention relates to the field of mobile communication base station antennas, in particular to an antenna for a multiple-input multiple-output antenna system suitable for multi-antenna communication work. [technical background] [0002] With the rapid development of mobile communication services, especially mobile data services, multi-antenna communication has become an important development direction due to its extremely high spectrum utilization. The base station of a multi-antenna system needs multiple antennas for independent transmission and reception, and its communication performance is directly related to the correlation between antennas and the difference in received power. When the correlation between antennas is weak, the anti-fading or space separation performance will be better. High, so as to achieve faster and more reliable communication under limited spectrum resources. [0003] The correlation between multiple antennas and the r...
