The effect of quasi-optics errors on reflector antenna performance
The use of quasi-optics feed systems with a reflector antenna allows multiple-frequency operation over a very wide bandwidth for remote sensing of the Earth and atmosphere from space. The errors in such a multichannel quasi-optical feed system must be controlled in order to limit the degradation of...

Summary: | The use of quasi-optics feed systems with a reflector antenna allows multiple-frequency operation over a very wide bandwidth for remote sensing of the Earth and atmosphere from space. The errors in such a multichannel quasi-optical feed system must be controlled in order to limit the degradation of system performance. These errors can be attributed to the presence of higher-order Gaussian modes, but the errors can be minimized if the quasi-optical system can be made independent of frequency. If volume limitations preclude a frequency-independent design, the amplitude of the higher-order Gaussian modes must be controlled.< > |
