| Résumé | In addition to the X-band polarization rotator (NRC ERB-735), two more polarizers were required for the J- and Ku-band receivers for the 150-foot paraboloid antenna at the Algonquin Radio Observatory. The specified restriction on variation in loss of VSWR with polarization rotation was rather stringent in order that source polarization measurements could be made. The design bandwidth 0.300 GHz centered at 6.500GHz for J-band, and 0.350 GHz centered at 13.50 GHz for Ku-band. Feed horns were also required for operation at the prime focus although the polarizers are suitable for Gregorian operation also. Calculated secondary patterns are presented for the prime-focus feed horns provided, as well as gain and aperture efficiency calculations. |
