Abstract
A device for at least one of receiving and transmitting electromagnetic radiation includes a feedhorn having a substantially smooth, electrically conducting inner surface extending from an open end to a feed end, the inner surface being substantially rotationally symmetrical about a longitudinal axis, wherein an orthogonal distance from a point on the longitudinal axis to the substantially smooth, electrically conducting inner surface increases monotonically as the point on the longitudinal axis is selected at successively greater distances from the feed end of the feedhorn towards the open end of the feedhorn such that a profile of the substantially smooth, electrically conducting inner surface of the feedhorn is monotonically increasing. The feedhorn has an operating bandwidth and the feedhorn provides a maximum of −30 dB cross polarization response over at least 15% of the operating bandwidth.
