During ACE 2, transversal actions between activities were promoted. In such a context, and due to their research interests, TKK and IETR decided to cooperate for measuring a lens in millimetric bands. This lens, a Half Maxwell Fish Eye structure fed by an open ended waveguide, has been designed in an IETR PhD-study for applications in the W-band. Due to IETR measurement facilities frequency limitations, no measurements could be performed above 110 GHz. Then, in the ACE 2 context, measurements were planned with TKK to characterize this lens at 110 GHz and 150 GHz. The 110 GHz frequency was chosen for two main reasons: to check lens capabilities with a WR-6 open ended waveguide as a feed, using IETR antenna test facility; and to make comparisons between IETR far-field antenna test range and TKK planar near-field antenna test range results. Presented measurements were performed in IETR in May 2008 and in TKK in June 2008.
