Abstract
The present disclosure includes a method for producing a multi-band waveguide reflector antenna feed. The antenna feed includes a first tube and a second tube. The first and second tubes are connected to form a concentric multi-band waveguide feed array. The first tube includes a surface(s) which is/are at least partially covered by metamaterial(s), thereby forming a first waveguide feed. The second tube also includes a surface(s) which is/are at least partially covered by metamaterial(s). A radial separation is established between the first tube and the second tube, thereby forming a second waveguide feed. The radial separation may be maintained between the first tube and the second tube by one or more of: a loading material, support structures, strings, and wires. The loading material, support columns, strings, and/or wires also structurally interconnect the first tube and the second tube.
