A New Focal Line for the East-West Arm of the Northern Cross Radio Telescope
The feed system of the 564 m long parabolic-cylindrical reflector of the Italian Northern Cross radio telescope operating at 408 MHz has been entirely reviewed to improve the overall performance of the antenna. As a result of a full-wave electromagnetic study, a decision has been made to replace the current illuminator consisting of 1488 half-wavelength dipoles and a corner reflector with 416 Yagi- Uda antennas. The new proposed feed system is presented in this paper and numerical results are compared to the original performance.
