5G NR Antennas: Sub-6 GHz Coverage and Capacity

5G NR Sub-6 GHz antennas serve the n77/n78/n79 and CBRS bands where wide instantaneous bandwidth and MIMO are essential to deliver the capacity gains promised by 5G.

Overview

Understanding 5g antennas starts with the physics of the band, then moves through pattern, gain, mounting and the practical constraints of a live deployment. Sub-6 GHz 5G trades the extreme bandwidth of mmWave for materially better range and in-building penetration, making 3.5 GHz the workhorse band for macro and fixed-wireless deployments.

Frequency Bands and Spectrum

The bands most relevant to 5g antennas are listed below. Each band brings different propagation, regulatory and antenna-size implications.

BandRange (MHz)Typical use
3.5 GHz (5G NR Sub-6)3400-36005G NR n78 / CBRS
3.3-3.8 GHz (5G Sub-6)3300-38005G NR Sub-6 GHz
2.3-2.7 GHz (TDD-LTE)2300-2700TDD-LTE / WiMAX / CBRS edge
Wideband (700-2700 MHz)700-2700Multiband / all-cellular

Recommended Antenna Types

The following antenna classes are best matched to 5g antennas:

Directional Panel Antenna

Sector / panel antennas delivering focused gain over a defined azimuth, used for base-station sectorization and fixed point-to-multipoint links.

MIMO Antenna

Multi-port spatially diverse antennas (2x2 / 4x4) for high-throughput MIMO links.

Omnidirectional Fiberglass Antenna

Collinear omnidirectional antennas in a UV-stable fiberglass radome for 360 degree outdoor coverage.

Applications and Use Cases

5G Antennas support a range of deployments. The most common are:

  • 5G NR Sub-6 GHz
  • 4G / 5G Base-Station Coverage
  • Fixed Wireless Broadband
  • TDD-LTE / WiMAX

Mounting and Installation

Sector panels are pole- or tower-mounted with mechanical and electrical downtilt; fixed-wireless CPE uses directional wall- or pole-mounted panels aimed at the serving cell.

Lightning Protection and Grounding

Tower-mounted 5G arrays require coordinated lightning protection: surge arrestors on each feed, bonded ground bars, and compliance with the site grounding plan.

Standards and Compliance

Designs and deployments in this area commonly reference:

  • 3GPP Release 15/16 NR
  • CBRS (FCC Part 96)
  • ETSI EN 301 908

Selection and Comparison

When narrowing down a model for 5g antennas, weigh these trade-offs:

  • Sub-6 GHz vs. mmWave
  • Single-port vs. 4x4 MIMO
  • Fixed downtilt vs. RET

Typical gain for this category is 12-18 dBi, usually terminated in a 4.3-10 or N-Female connector, though the interface can be customized.

Frequently Asked Questions

What frequency bands do 5g antennas use?

5G Antennas typically operate across 3.5 GHz (5G NR Sub-6), 3.3-3.8 GHz (5G Sub-6), 2.3-2.7 GHz (TDD-LTE), and Wideband (700-2700 MHz). The primary band spans 3400-3600 MHz.

How should 5g antennas be mounted?

Sector panels are pole- or tower-mounted with mechanical and electrical downtilt; fixed-wireless CPE uses directional wall- or pole-mounted panels aimed at the serving cell.

What antenna gain is typical for 5g antennas?

A typical gain range is 12-18 dBi. Higher gain narrows the beamwidth and extends range, so the right value depends on whether you need broad coverage or a focused long-distance link.

Which applications are 5g antennas best suited for?

Common applications include 5G NR Sub-6 GHz, 4G / 5G Base-Station Coverage, and Fixed Wireless Broadband. Sub-6 GHz 5G trades the extreme bandwidth of mmWave for materially better range and in-building penetration, making 3.5 GHz the workhorse band for macro and fixed-wireless deployments.

What connector do 5g antennas normally use, and can it be changed?

The usual interface is 4.3-10 or N-Female. The connector and cable assembly can be customized — SMA, N-type, TNC, BNC, FAKRA and IPEX options are available on request.

Do 5g antennas need lightning protection?

Tower-mounted 5G arrays require coordinated lightning protection: surge arrestors on each feed, bonded ground bars, and compliance with the site grounding plan.

Which standards apply to 5g antennas?

Relevant standards and references include 3GPP Release 15/16 NR, CBRS (FCC Part 96), and ETSI EN 301 908.
