Measuring instruments

Description

DTU is establishing the DTU Electromagnetic Test Centre (DTU ETC) for high-accuracy testing of antennas, components and circuits, as well as materials and scattering structures. The DTU ETC will comprise several laboratories in the existing building 353 and a new building 357. Phase I of the DTU ETC was initiated in 2016 and completed in 2018, while phase II was initiated in 2017 and will be completed in 2022. This procurement includes the following 3 different test facilities: — millimetre-wave antenna test facility, — millimetre-wave component and circuit test facility, — multipurpose antenna test facility. Description of test facility: ETC millimetre-wave antenna test facility for determining the radiation pattern and the gain of antennas. This could be high, medium, or low directivity/gain antennas, isolated antennas fed through a coaxial cable or a waveguide, or integrated/on-chip antennas fed through an integrated transmission line. It is anticipated that this measurement facility will be a spherical near-field configuration that may also serve as a far-field configuration for higher frequencies and proper electrical size of the antenna under test; alternatively, this measurement facility may be a compact range configuration. Description of test facility: millimetre-wave component and circuit test facility, which is one of the DTU ETC laboratories and will be located in the new building 357. The essential requirement to this facility is to provide interference-free environment for testing high sensitivity electronic components and integrated circuit chips in the extended frequency range. Description of test facility: ETC multipurpose antenna test facility for determining the radiation pattern and the gain of relatively heavy and large antennas, and for gain calibration of gain reference antennas. These objectives require a combination of a single-probe arc/arm-over-azimuth scanner providing spherical near-field measurements and an extrapolation range.
