摘要： A feed network may include a cylindrical common waveguide terminating in a common port and an orthomode transducer having a first port for coupling a first linearly polarized mode to the cylindrical common waveguide and a second port for coupling a second linearly polarized mode to the cylindrical common waveguide, the second linearly polarized mode orthogonal to the first linearly polarized mode. A filter-polarizer element may be disposed within the cylindrical common waveguide. The filter-polarizer element may be rotatable about an axis of the cylindrical common waveguide. The filter-polarizer element may be configured to cause a predetermined relative phase shift between a first signal and a second signal propagating in the cylindrical common waveguide. The filter-polarizer element may be further configured to suppress propagation of at least one undesired mode in the cylindrical common waveguide.

摘要： A significant problem in rotationally symmetric dual reflector systems is the blockage caused by the sub-reflector. This blockage produces lower gain and higher side lobes. The invention disclosed herein can be used to minimize or eliminate the blockage effects. In its simplest form, the invention is to place a hole in the sub-reflector. This allows radiation to by-pass the main reflector and replaces the radiation which is blocked by the sub-reflector. In general this radiation and the radiation which progresses on the standard path, which includes the main reflector, will not be in a useful phase and amplitude relationship. However by appropriate design of the inner and outer sub-reflector surfaces, the main reflector surface, the feed aperture, the dielectric support and the possible use of a dielectric rod, the phase and amplitude relationships can be controlled. The invention also applies to cylindrical dual reflector systems which are symmetric about a plane.
摘要翻译：旋转对称双反射器系统中的一个重大问题是由副反射器引起的阻塞。这种堵塞产生较低的增益和更高的旁瓣。本文公开的本发明可用于最小化或消除堵塞效应。在其最简单的形式中，本发明是在子反射器中放置一个孔。这允许辐射绕过主反射器并且替换被子反射器阻挡的辐射。通常，这种辐射和在包括主反射器的标准路径上进行的辐射将不是有用的相位和幅度关系。然而，通过适当设计内部和外部副反射器表面，主反射器表面，馈电孔，电介质支架和可能使用介质棒，可以控制相位和幅度关系。本发明也适用于关于平面对称的圆柱形双重反射器系统。
