Planar Nearfield Scanner in our anechoic chamber

The fully accredited antenna laboratory offers precise, high-quality measurements, tests, and calibrations of almost all kind of antennas.

The antenna laboratory is accredited for the most important national and international regulations and guidelines. The covered accreditation-scope includes measurement procedures for the point-to-point (PTP) and point-to-multipoint (PTMP) radio-link antennas, as well as antennas for stationary and mobile wireless radio services in a frequency range up to 50 GHz.

The portfolio of custom-tailored and standardized antenna test projects conducted in the recent past ranges from „simple“ isotropic antennas to antennas with medium and high gains as well as broadband antennas. Based on customer’s specifications we design, build and calibrate high-quality reference antennas also.

Anechoic Chamber (Figure above)

The completely shielded (pyramidal absorbers) equipped anechoic chamber allows for both the measurement of near-fields and far-fields as well. The very low reflections of the absorber configuration enables measurements over a very wide frequency range - from 400 MHz up to 64 GHz. Utilizing the installed roll-over-azimuth-over-elevation positioner full 3D radiation patterns of antennas, at a minimum impact from the positioner device, can be performed at very high-accuracies.The planar near-field scan capability consist of a X-, Y-, Z- scanner unit, which is controlled by a modern, powerful software (MIDAS). For high-gain antennas this is the most appropriate method to determine the 3D radiation pattern.

		Outdoor Measurement Range The Outdoor range - from our companies roof to a separate tower 110 m apart – allows for the characterization of larger and heavier antenna devices, e.g. satellite or radio link antennas. Several transmit antennas can be mounted and re-directed towards the AUT. Thus, it enables us to characterize the polarization properties of an antenna. Reference Antennas Reference antennas are required for the precise measurements of antenna gains. Typically, standard-gain-horns, logarithmic-periodic horns, or dipoles in a frequency range from 30 MHz up to 75 GHz are used for this. For our planar near-field measurement capability we make use of a set of linear-polarized reference antennas. For circular-polarized antennas circular-polarized reference antennas are utilized accordingly.
Outdoor Measurement Range, Far-fields
Electronic Controllable Antenna – Far-field measurements An Imposing Example One of the largest antennas, which has been measured in our anechoic chamber ever, was an electronically steerable device for worldwide communications. The intended use of the antenna is the multimedia-communication from cruise liners - at all weather conditions - via satellite by tracking the satellite position electronically. The antenna under test (AUT) consists of an array of 32 x 8 radiating elements with 64 T/R-modules. Frequency of operations is at L-bands. The antenna was completely characterized in the near- and in the far-field range.
