5G Massive MIMO Antenna Array, 5G NR Base Station Antenna Manufacturers

This page mentions manufacturers of 5G Massive MIMO Antenna Array for 5G NR base station. The specifications of massive MIMO antenna Array for 5G NR base station are also mentioned. As we know, 5G NR stands for Fifth Generation New Radio.

What is MIMO Antenna Array in 5G NR ?

Massive MIMO refers to system having multiple antenna elements in the form of active antenna array used to transmit multiple data streams in the desired direction. It helps to increase system capacity, data throughput and coverage.

Massive MIMO is also called as mMIMO. It employs beamforming to direct energy in the desired user direction to mitigate interference from other users.

MU-MIMO in 5G NR

There are two types (SU-MIMO and MU-MIMO) based on number of users served by Base Station or eNB. In SU-MIMO, all the streams of antenna array are focused on single user. In MU-MIMO, multiple streams are focused on multi users. Each of these streams of MU-MIMO antenna system provide radiated energy to more than one users simultaneously. Massive MIMO uses MU-MIMO in which multiple radio transceiver units are combined with anetnna elements on single active unit.

5G Massive MIMO Antenna Array

;Both FDD and TDD are used with massive MIMO. TDD operates on same frequency on downlink (DL) and uplink (UL). FDD operates on different frequencies for DL and UL. TDD is better than FDD due to channel reciprocity. With FDD, feedback overhead increases with antenna elements.

Example : 64T64R Massive MIMO Antenna
Here 64T64R refers to 64 transmit and 64 receive antenna elements with total of 128 antenna elements/ It uses 64 transceiver units, each are mapped to two antenna elements. Both uses different polarizations to transmit/receive different unique data streams.

Massive MIMO Antenna Array Specifications

Following specifications or parameters are considered for selecting the massive MIMO antenna array for 5G base station network installation.
• Frequency band of operation (e.g. n41/B41 (2.5 GHz) )
• Antenna Bandwidth (e.g. 200 MHz)
• Transmit power (e.g. EIRP of 68 dBm)
• Number of antenna elements (16/32/64/96 dual polarized)
• Maximum gain ( e.g. 17.5 dBi )
• Antenna Array Efficiency (e.g. 67 %)
• 3 dB Beam width (e.g. 18 degree)
• Return Loss (e.g. -15 dB)
