1. A feed with a longitudinal axis, comprising:
- a waveguide;
at least one corrugation(s) extending from an end of the waveguide;
the corrugation(s) coaxial with the longitudinal axis, forming an extension of the waveguide;
the corrugation(s) having an end face angle less than 90 degrees with respect to the longitudinal axis;
the waveguide and the at least one corrugation(s) extending from the end of the waveguide forming a first side feed formed as a unitary element also including a central feed;
the central feed spaced away from the first side feed and having a central feed longitudinal axis that is parallel to the longitudinal axis of the side feed.

Abstract
A feed having a waveguide with a longitudinal axis. A plurality of corrugations extending from an end of the waveguide. The corrugations coaxial with the longitudinal axis, forming an extension of the waveguide. The corrugations having an end face angle less than 90 degrees with respect to the longitudinal axis to squint the feed beam.

11. A feed assembly, comprising:
-
a first side feed having a waveguide with an open end; at least one corrugation(s) extending from the open end of the waveguide; the corrugation(s) coaxial with a first side feed longitudinal axis, forming an extension of the waveguide with an increasing diameter; the corrugation(s) having an end face angle less than 90 degrees with respect to the feed waveguide longitudinal axis; and a central feed spaced away from the first side feed and having a central feed waveguide longitudinal axis that is parallel to the side feed longitudinal axis; the first side feed and the central feed extending from a base plate, the first side feed and the central feed having a vertical offset along a horizontal axis.

12. A method for manufacturing a feed, comprising the steps of:
-
forming a waveguide having at least one corrugation(s) extending from an end of the waveguide; the corrugation(s) coaxial with a longitudinal axis of the waveguide, forming an extension of the waveguide; the corrugation(s) having an end face angle less than 90 degrees with respect to the longitudinal axis; the waveguide and the at least one corrugation(s) extending from the end of the waveguide forming a first side feed formed as a unitary element also including a central feed;
the central feed spaced away from the first side feed and having a central feed longitudinal axis that is parallel to the longitudinal axis of the side feed. - View Dependent Claims (13, 14, 15, 16)
