This paper addresses the design and analysis of a 8.5m dual-offset reflector antenna for S-Band weather RADAR applications, we well as feed and antenna test results showing compliance to very stringent beam symmetry, cross-polarization, and power han

Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation.
This paper describes the feed upgrade effort to an existing 9m dual-offset reflector antenna operating at S-band for weather radar applications. The new feed, designed to upgrade the existing operational capabilities, fits mechanically in the existin

Discussed is a dual mode coaxial horn for prime focus applications. A coaxial horn is excited by a TE11 mode generator - the dipole. The result is an antenna pattern with an axially symmetrical main beam, and low sidelobes. Further considerations sho
