Antenna Test chambers

FOR NEAR-FIELD AND FAR-FIELD MEASUREMENTS

The shielding in our premium antenna test chamber is based on a traditional Faraday cage as the main structure of the room. This provides a premium shielding attenuation of over 100dB within the testing frequency range. 

We also developed a basic shielding chamber with shielding attenuation of 25dB or more, using a cost-effective steel structure that can even be installed by your own team.

In the section below, you can see whether a basic chamber is sufficient for your testing needs.

Comtest Favicon

Premium Antenna Test Chamber

The perfect choice for accurate measurements of antennas on mobile, telecom, and wireless communication equipment. This high-performance Faraday cage effectively blocks ambient noise while ensuring total confidentiality.

It is optimised for accuracy and features our own polystyrene absorbers to minimise reflections, providing superior measurement reliability.

Your new chamber will be used for:

Testing High-Power Antenna/Radars

or

Testing at Classified Frequencies

or

Testing Passive Inter-Modulation (PIM)

or

Testing Hardware in the Loop

or

Testing in the Proximity of strong Ambient Signals

Basic Antenna Test Chamber

This cost-effective, DIY solution for antenna measurements is constructed with a lightweight frame and our own polystyrene absorbers mounted directly onto the structure. It offers adequate shielding effectiveness for most testing requirements. 

With only essential carpentry tools and skills, you can assemble the chamber yourself, making it an ideal option for schools, universities, and budget-conscious companies. But you can always count on our installation team as part of our worry-free approach.

Mobile Absorber Walls

Mobile absorber walls are an ideal solution for various test setups, including circular ones, and can be stored outside the chamber. We offer standard configurations, custom dimensions, walls with adjustable heights, and absorber wall connections. The walls arrive as a self-assembly kit with clear installation instructions.

Microwave Absorbers

We offer a selection of pyramidal RF microwave absorbers with an operating frequency from 200 MHz to 50 GHz for antenna testing. These absorbers are made from polystyrene, a closed-cell material that encapsulates the high-loss dielectric material in our products, thereby preventing the leakage of dust particles.

Happy clients

Test execution very close to real-life

“Comtest is extremely flexible, forward-thinking and fast.
We are satisfied with our EMC chamber, which is set up to
provide us with load possibilities far beyond anything possible
with third-party testing solutions. This makes our test execution
very close to real-life usage of our products.”

Director of Test, Validation and Engineering Support

Essential to ensure reliable testing

“NXP is located on the High-Tech campus in Eindhoven.
Here the electromagnetic spectrum is quite crowded.
Shielded rooms are essential to ensure reliable testing.
Our 3 Comtest RF-shielded facilities have never sat empty,
which speaks volumes regarding their value to us.”

Clear and candor way

“The clear and candor way Comtest
communicates, made it easy to
effectively determine the scope of
the project.”

No risk of incompatibility

“Comtest delivers a turn-key solution,
so there’s no risk of incompatibility or
subpar calibration.”

Omar Romero
Engineer

Extremely motivated

“The Comtest team was extremely motivated
to create a unique type of chamber system that
hasn’t been built before.”

Reputation for quality

“For the expansion of our testing capabilities we worked
with Comtest for the construction of a new,
oversized testing chamber. We chose to work with Comtest
based on their reputation for quality and the fact
that they’re a Dutch company.”

Works very fast and thoroughly

“At Emitech, there are over 40 different types of testing
chambers to fit any testing. Comtest has built many of them
and works very fast and thoroughly. They completed our latest
3M SAC setup within one week. We look forward to working
with Comtest on future projects.”

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
