5G Antennas

What are 5G antennas?

A 5G antenna is a key component in a 5G New Radio network, responsible for transmitting and receiving wireless signals or electromagnetic wave energy. Compared with 4G antennas, 5G antennas are designed significantly differently to adapt to the characteristics of 5G technology.

5G NR (New Radio) is a core component of the fifth generation of mobile communication technology (5G) and is a new OFDM-based air interface design. It is designed to deliver higher speeds, lower latency, greater connection density, and greater energy efficiency than previous generations of technology, such as 4G LTE.

Characteristics of 5G antennas

Higher frequency band usage

5G networks use higher frequency bands, including millimeter-wave bands (e.g., above 24 GHz), which makes antenna design require smaller dimensions to accommodate the wavelengths of the higher bands.

Beamforming technology

G antennas make extensive use of beamforming technology to improve signal transmission efficiency and coverage by precisely controlling the direction of the signal.

Massive MIMO (Multiple Input Multiple Output)

5G antennas support massive MIMO technology, in which the antenna array contains a large number of transmitting and receiving units, thus dramatically increasing the data transmission rate and network capacity.

Miniaturization and integration

To adapt to the high-frequency band and high-density deployment requirements of 5G networks, the 5G antenna design is more miniaturized and integrated.

Basic concepts and features of 5G NR

Frequency Range

5G NR is divided into two main frequency ranges, with Frequency Range 1 (FR1) covering the frequency band below 6 GHz and Frequency Range 2 (FR2) covering the millimeter-wave band (20-60 GHz).

Carrier bandwidth and subcarrier structure

Supports wider carrier bandwidth and flexible subcarrier spacing configurations to accommodate different application scenarios and requirements.

Waveform and multiple access technology

New waveforms (e.g. CP-OFDM) and multiple access schemes (e.g. Non-Orthogonal Multiple Access NOMA) are adopted to improve spectral efficiency and connectivity.

Flexible frame structure

Dynamically configurable frame structure and time slot design to support ultra-low latency communications.

BWP (Bandwidth Part)

Allows different bandwidth parts to be defined within a carrier, each BWP has its numerology (parameters such as subcarrier spacing) to adapt to different service requirements.

What are the types of new 5G antennas?

New 5G antennas can be categorized into various types according to their design, purpose, and shape such as PCB antennas, flexible PCB antennas, microstrip antennas, rubber duck antennas, magnetic mount antennas, adhesive patch antennas, yagi antennas, sector antennas, fiberglass antennas, parabolic grid antennas, panel antennas, and so on.

Applications of 5G antennas

5G antennas are widely used in various scenarios, including the following application scenarios.

Urban coverage

In urban areas, 5G antennas are installed at base stations, street lights, building surfaces, etc. to provide extensive coverage.

Indoor coverage

In indoor environments such as shopping malls, airports, offices, etc., 5G antennas are used to provide high-speed wireless network connectivity.

Macro base stations

5G NR antennas are widely used in macro base stations to provide extensive network coverage and high-speed data transmission services.

Small base stations and micro base stations

In dense urban areas or indoor environments, 5G NR antennas are also deployed in small base stations and micro base stations to provide higher network capacity and finer coverage.

IoT and smart cities

5G NR antennas also support communication between IoT devices, providing reliable network connectivity for application scenarios such as smart cities and smart homes.

Glass antenna

With the development of material technology, 5G NR antennas can even be integrated into everyday objects such as glass windows, enabling more covert and efficient network deployment.

Specialized applications

For example, in fields such as self-driving vehicles, telemedicine, and industrial automation, 5G antennas provide stable, high-speed communication support.
