Invited talk 8: Measurement of the 664 GHz feed horn for the ICI instrument of the MetOp SG satellite

This paper presents the results of the antenna pattern measurements conducted on the Ice Cloud Imager 664 GHz feed horn at the ESTEC Sub-mmwave Scanner (SmS) in support to the ICI instrument of the MetOp-SG program. Very good agreement between simulations and measurements was obtained, both in the co- and cross-polar component. The measured peak directivity was 26.28 dBi ± 0.13 dB while the simulated one was 26.35 dB.
