Antenna Measurement Hall

Measuring antennas and antenna systems in an anechoic environment

One of the key components of any radio system is its antenna. Efforts to measure and optimize the antenna often lead to a jump in quality for the entire system. During testing, it is possible to take the antenna’s operational environment into account to a certain degree. Our antenna measurement hall offers all the necessary test infrastructure for this purpose.

At Fraunhofer IIS’s antenna measurement hall, antennas and complete antenna systems for frequencies ranging between 700 MHz and 110 GHz can be exactly measured and functionally verified. Measurement takes place in a fully shielded absorber hall in order to prevent external interference and to ensure precise and reliable results.

Anechoic environment

Our antenna measurement hall is completely lined with pyramid-shaped HF absorbent material. The absorbers allow us to carry out precise measurements at frequencies above 700 MHz. Thanks to the high-quality equipment and its special design, the chamber dampens potential sources of interference from the surrounding area by up to 100 dB. To ensure that it is free of vibrations from the building, the anechoic room is located in the basement – essentially detached from the rest of the structure.

Flexible measurement range

Currently, the facility accommodates measurements from 700 MHz up to 110 GHz. Designed to handle both short and long distances, the measurement hall is suitable for near- and far-field measurements. Every installation is customized to meet the requirements of the respective analysis.

Nearly all antenna parameters can be determined with just one measurement. Special parameters, such as signal transit time, can also be analyzed.

All antenna types

The spherical near-field measurement technique can be used to measure virtually any antenna type, no matter whether they are low- or high-gain devices. Size doesn’t matter either – an antenna with a diameter of just a few millimeters integrated into an embedded system can be analyzed just as easily as antennas larger than a meter.

Our test and measurement services:
support for your antenna development

As an application-oriented research institute, we offer independent test and measurement services for virtually all antenna types in the 700 MHz to 110 GHz range. All measurements are conducted by our experts in the in-house antenna measurement hall. The results are provided in a detailed and comprehensible test report outlining all measurements and antenna parameters.

Your benefits:

  • Independent tests and measurements
  • Detailed test report
  • On request: optimization and further development of antenna design by our development team
