P-band feed design and optimization for compact antenna test range

A single polarized P-band feed, consisting of an array of 4 high gain log-periodic elements has been designed, manufactured and tested for use as illuminator in a compact antenna test range. This paper briefly describes the antenna design trade-off activity, selection of the candidate antenna technology, manufacturing and final testing including considerations on the associated measurement uncertainty in the SATIMO SG-64 multiprobe spherical near field test range used for the acceptance testing.
