The focus of this research was the design, optimization, and measurement of a monotonically profiled, smooth-walled scalar feedhorn with a diffraction-limited ~14° FWHM (full width at half maximum). It is an easier-to-manufacture, smooth-walled feed that approximates the properties of excellent beam symmetry, main beam efficiency, and cross-polar response over wide band-widths, but over a finite bandwidth.

This work was done by Edward Wollack and David Chuss of Goddard Space Flight Center, and Lingzhen Zeng and Charles Bennett of Johns Hopkins University. NASA is seeking partners to further develop this technology through joint cooperative research and development.
