The anechoic room allows for (active) antenna measurements in a frequency band ranging from 800MHz up to 12.4GHz. Measurements are performed on an Agilent N5242A 4-port PNA-X Vector Network Analyser or a Rohde and Schwarz FSV40 Spectrum Analyser with optional 60 GHz mixer. Transmission measurements are performed in our full anechoic chamber (dimensions of the shielded room: 8.1m x 3.9m x 3.6m), over a transmission length of 4 to 5m (quiet zone diameter 1m). Scientific Atlanta Standard Gain Horns (SGH) are used as transmitter antenna. For polarization measurements, the transmitting SGH is mounted on an Orbit/FR AL-360-1P Polarization Positioner placed on a TX Antenna Mast covered with radiation absorbing material (RAM). For 3D radiation pattern measurements, the antennas are mounted on the dielectric belt-driven rotator mast (AL-DBDR-3g), able to rotate a load up to 12kg along azimuth and roll.
For wireless communication experiments in realistic environments, the group has different software defined radio testbeds at its disposal to quickly set up wireless multiple-input multiple-output communication links. Our Signalion HaLo 420 testbed emables synchronous 4x4 MIMO testbed in the 2.45 GHz ISM and 5-6 GHz band, whereas our HaLo 430 testbed provides a 4x4 phase-coherent and synchronous MIMO channel in the 2.45 GHz ISM band.
In addition, 12 ETTUS N210 modules are available for wireless SISO/MIMO communication in the frequency range 400 MHz to 4400 MHz, and 14 National Instruments FlexRIO modules with programmable FPGA for up to 14x14 MIMO and cooperative wireless communication links in the frequency range 1.2GHz to 6GHz.
A wireless testbed for Ultra-WideBand (UWB) localization and communication, composed on 25 PulsON P400 RCM modules operating in the 3.1GHz-5.3GHz UWB band.
Besides owning some smaller state-of-the-art multiprocessor servers for debugging and testing our full-wave solvers, the Electromagnetics group has access to the Tier 1 Supercomputer of Ghent University.
