Abstract
A feed assembly for a multibeam antenna having a GRIN lens. A feed plate is attached to the GRIN lens and has a port for each channel of the antenna. A waveguide is associated with each port, each waveguide having an opening for transmitting a signal into the GRIN lens. A plug associated with each waveguide and made from the same material as the lens, is configured at a port end to fit into a port and configured at a waveguide end to fit into the associated waveguide.
