On the design of the feed horns for the karoo array telescope dish antennas

This paper describes the design of the feed horns for the Karoo array telescope (KAT) experimental prototype dish. The feed horn is a dual polarized circular horn with a linearly polarized circular pattern operating from 1414 to 1670 MHz. The horn is excited with a quad-ridged ortho-mode transducer...

Zusammenfassung:This paper describes the design of the feed horns for the Karoo array telescope (KAT) experimental prototype dish. The feed horn is a dual polarized circular horn with a linearly polarized circular pattern operating from 1414 to 1670 MHz. The horn is excited with a quad-ridged ortho-mode transducer (OMT).
