5G antenna tuner manufacturers | Antenna tuning in 5G smartphone

This page describes antenna tuning basics in 5G smartphones. It mentions list of 5G antenna tuner manufacturers or vendors.

What is Antenna tuning in 5G smartphones ?

Antenna tuners are devices placed between transmitter and antenna in order to increase the EM (Electro-Magnetic) signal radiation by minimizing mismatch and absorption losses.

Antenna tuners are categorized into aperture tuners and impedance tuners. Aperture tuners are placed at various locations in antenna design which help in improving total antenna efficiency. Impedance tuners are placed between RF front end and antenna which help in reducing mismatch losses over wide frequency range.

In latest technologies, number of antennas have been increased in order to support higher data rates using MIMO and CA (Carrier Aggregation) techniques. In 5G smartphones number of antenna requirements have been increased from 4-6 to about 8 or more.

Antenna tuners deliver following benefits in WiFi MIMO, 4G LTE and 5G NR (New Radio) systems.
➨Offers higher data rates.
➨Improves signal quality and coverage.
➨Enhances battery life.
➨Smaller phone designs by embedding appropriate compact tuning solutions.
➨Increased antenna efficiency over wide bandwidth.

Antenna Tuning methods

The figure depicts antenna tuning methods. Without tuning it is not possible to achieve maximum radiated power due to increased mismatches and higher absorption loss of RF signal. Aperture tuning and impedance tuning increases radiated power due to reduction in mismatches and RF signal absorption losses. Both aperture tuning and impedance tuning methods offer various antenna tuning solutions such as switch tuners, capacitive tuners and combination of both.
