Abstract
This paper describes the design, manufacturing and performance test results of a submillimeter antenna (ANT) of SMILES at 0.64THz. The design of ANT is aiming at achieving high beam efficiency, low side lobe levels and a high thermal stability (Noguchi, 2003)(Noguchi et al., 2004). In this paper, a manufactured engineering flight model (EFM) of ANT and its measured performance, such as surface errors of reflectors, near- field distribution and far-field radiation pattern estimation from the near field measurements are presented. Measured performance has in good agreement with the design and the successful performance of EFM has been confirmed.
