Project C05 - Efficient On-Chip Antennas for THz Systems
Principal Investigator: Dr. Andreas Rennings, UDE
During the 1st phase of MARIE, an automatic characterization system for mm-wave antennas based on spherical positioning has been developed. It features network-analysis based far field and S-parameter measurement, currently up to 330 GHz, depending on the used frequency extender. The antenna under test is centered in a spherical coordinate system and fed by either on-wafer probe or waveguide, whereas the receiving antenna moves along the surface of the hemisphere, enabling a far field measurement of amplitude and phase pattern [1].
