Description

Clamping device for antenna {CLAMPING APPARATUS FOR ANTENNA}

The present invention relates to a clamping device for an antenna, and more specifically, to a clamping device for an antenna that allows efficient arrangement of antenna devices in a dense installation space and facilitates direction control 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. The transmitter transmits different data through each transmit antenna, and the receiver transmits different data through each transmit antenna. is a spatial multiplexing technique that separates transmitted data through appropriate signal processing.

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

4G LTE-advanced uses up to 8 antennas, and products equipped 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, when Massive MIMO technology is introduced, 3D-Beamforming becomes possible, so it is also called FD-MIMO (Full Dimension).

In Massive MIMO technology, as the number of ANTs (antennas) increases, the number of transmitters and filters also increases. Nevertheless, due to lease costs or space constraints at the installation location, the reality is that RF components (Antenna/Filter/Power Amplifier/Transceiver etc.) are made small, light, and cheap, and Massive MIMO requires high output to expand coverage. Power consumption and heat generation due to such high output are acting as negative factors in reducing weight and size.

In particular, when installing a MIMO antenna in a limited space in which modules containing RF elements and digital elements are combined in a stacked structure, compactization and The need for miniaturized design is emerging, and there is a strong demand for free direction control of an antenna device installed on a single support pole.
