| Popis: | A short-backfire antenna (SBA) with corrugated structure on the aperture edge of the main reflector is designed to suppress sidelobe and enhance the isolation. The corrugated SBA is suitable for closed-pack antenna array. Early prototype antenna measured results indicate that the radiation pattern is well fit to the design and simulation. The simulation also indicates that the spill over temperature is below 11K over 700- 900MHz if the SBA is integrated to the 100-meter Green Bank Telescope. |
