The effect of quasi-optics errors on reflector antenna performance
Abstract
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.
