Antenna Measurement Rooms

Test your latest technologies. Global EMC’s antenna measurement rooms are designed and built to meet the exacting performance of antenna measurement. Whether it’s the latest 5G, telecommunications, radar or other wireless technologies each chamber is uniquely designed to meet the needs of the antennas under test.


Adaptable and configurable for military, marine, aerospace and commercial applications each facility gives the user a reliable and repeatable testing environment for antenna testing and antenna specification characterization.

5G Technologies

Development of the next generation 5G technologies. With anechoic performance of up to 86 GHz and antenna positioner equipment available.

Shield Effectiveness - Global EMC


All facilities have a high-performance RF shielding to enable an inert environment free of unwanted ambient interference and signals.

Antenna Measurement Rooms features

A faraday cage is provided to exclude unwanted ambient interference and signals from outside the room. This makes the internal space within the facility a controlled and noise-free environment. The shielding can be provided with high performance to 40 GHz.


The shielding is internally lined with anechoic material of pyramidal absorbers to all surfaces including the floor. This creates a fully anechoic chamber with specialist “walkway” absorbers on the floor. This enables access to the test positions and for maintenance purposes. The absorbers are specified to the exact frequency range required, reducing measurement uncertainties and increasing the performance of the facility.


Field probe positioners, turntables and antenna positioning systems are available to complete the turn-key installation.

High-Performance Anechoic Lining

Pyramidal Absorbers – Doped foam microwave absorber is installed to all walls, ceiling and floor area. The length of the absorber is selected to the frequency and performance required. Compliant to NRL8093 parts I, II and III for fire safety the GDS range absorber is perfect for high performance from 1 GHz +.


Specialist “walkway” absorber is provided from each door opening to positions within the room. This provides access to the room without compromising the anechoic performance.

Shielding Effectiveness tested to EN 50147-1

Every Global EMC anechoic chamber is provided with a Faraday cage shield. The shielded enclosure provides both an area free from external ambient signals but also protection during Immunity testing for personnel working outside the chamber.

The measure of shielding performance is conventionally known as “shielding effectiveness”. 100dB in plane and microwave frequencies is generally regarded by most standards as a very high level of shielding suitable for scientific use.

Global EMC offer two levels of shielding Standard and Extended Performance. Standard performance is suitable for most shielding requirements and is typically seen in commercial testing situations. Extended Performance is usually used in high-performance Military applications along with certain high frequency needs.
