Base station antenna with same-frequency mutual coupling effect reducing device

Abstract

The invention provides a base station antenna with a same-frequency mutual coupling effect reducing device, which comprises a metal base, an outer cover, a plurality of columns of antenna units and decoupling devices, and is characterized in that the decoupling devices are arranged between two adjacent columns of antenna units; the frequencies of the multiple columns of antenna units are the same, and the distance S between every two adjacent columns of antenna units is smaller than 1 / 4 of the center frequency wavelength of the antenna units and larger than 1 / 10 of the center frequency wavelength of the antenna units; the length L of the decoupling device is greater than the length of the antenna unit, the height H is equal to the height of the antenna unit, and the width D is greater than 1 / 16 of the central frequency wavelength of the antenna unit. The base station can be provided with more antennas by reducing the distance between the multiple columns of antenna units so as to enlarge the communication capacity of the base station, and the decoupling device is arranged between the two adjacent columns of antenna units so as to reduce the mutual coupling effect between the adjacent antenna units, so that the mutual coupling effect between the antenna units is effectively reduced under the condition that the design size of the base station antenna is met.

Description

technical field

[0001] The present application relates to the technical field of mobile communication, and in particular to a base station antenna equipped with a same-frequency mutual coupling effect reducing device. Background technique

[0002] In order to adapt to the development of mobile communication technology, especially the continuous development of the fifth generation mobile communication based on massive MIMO (Multiple-Input Multiple-Output) technology, the number of antennas (including antennas in mobile terminals or base stations) presents Doubling trend.

[0003] Research shows that the capacity of the communication system increases linearly with the increase of the number of antennas when the output power is constant, the signal-to-noise ratio is constant, and the antenna elements are not correlated with each other. Therefore, the greater the number of antennas installed in the same base station, the greater the communication capacity. However, the large-s...
