Description

Clamping device for antenna {CLAMPING APPARATUS FOR ANTENNA}

The present invention relates to a clamping device for an antenna, and more particularly, to an antenna clamping device capable of efficiently arranging an antenna device in a dense installation space, as well as easily adjusting the direction of the antenna device.

Wireless communication technology, for example, MIMO (Multiple Input Multiple Output) technology, is a technology that dramatically increases data transmission capacity by using multiple antennas. A transmitter transmits different data through each transmission antenna, and a receiver Is a spatial multiplexing technique that classifies transmission data through appropriate signal processing.

Accordingly, as the number of transmit/receive antennas is simultaneously increased, the channel capacity increases and more data can be transmitted. For example, if the number of antennas is increased to 10, a channel capacity of about 10 times is secured using the same frequency band compared to the current single antenna system.

In 4G LTE-advanced, up to 8 antennas are used, and products with 64 or 128 antennas are currently being developed in the pre-5G stage, and base station equipment with a much larger number of antennas is expected to be used in 5G. , This is called Massive MIMO technology. While the current cell operation is 2-Dimension, it is also called FD-MIMO (Full Dimension) because 3D-Beamforming becomes possible when Massive MIMO technology is introduced.

In Massive MIMO technology, as the number of ANTs increases, the number of transmitters and filters increases accordingly. Nevertheless, it is a reality to make RF parts (Antenna/Filter/Power Amplifier/Transceiver etc.) small, light and inexpensive due to the lease cost and space constraints of the installation site, and Massive MIMO requires high output for coverage expansion. Power consumption and heat generation due to such high output are acting as negative factors in reducing weight and size.

In particular, when a MIMO antenna in which RF elements and modules implemented with digital elements are combined in a stacked structure is installed in a confined space, compactness of a plurality of layers constituting the MIMO antenna and The necessity of miniaturization design has emerged, and there is a strong demand for free direction control of an antenna device installed on one support pole.
