摘要： A tunable polarizer having a 90 degree phase shift section and two adjustable, or rotatable, 45 degree phase shift sections. Each section is separated by spacer to maintain independence and avoid interaction. When the two 45 degree phase shift sections and are orthogonal to each other, the polarization detected is determined by the 90 degree phase shift section which provides compatibility with circularly polarized signal. When the two 45 degree phase shift sections and are aligned, the polarizer is in a linear polarization compatibility mode.

摘要： Equalized offset fed east and west shaped reflectors (12) and (14) and technique for producing the same are provided herein. A first shaped reflector (12) has a first shaped reflective surface (3) formed to provide a first shaped beam radiation pattern (22). Dimensional deviations such as deviations (X) and (Y) are measured between the first shaped reflective surface (13) and a parent surface (30). A second shaped reflector (14) is formed with a shaped reflective surface (15) which has dimensional deviations superimposed on the other side of the parent surface (30). The second shaped reflector (12) is rotated 180 degrees relative to the first shaped reflector (14). The first and second shaped reflectors (12) and (14) are then placed in a configuration opposite one another and have shaped beam radiation patterns (22) and (24) which are substantially equal to one another. In addition, feed horns (18) and (20) are operatively coupled to the first and second shaped reflective surfaces (13) and (15) respectively.

摘要： A system (12) operative with at least one electromagnetic wave to produce a circularly polarized wave includes a plurality of polarizer sections (56) disposed along a direction of propagation of one electromagnetic wave. The polarizer sections have opposed rows of phase shifting elements, in the form of rods (76), which are adjusted to provide a match to the orthogonal components of the wave. Penetration and spacing of phase shifting elements within each of the polarizing sections attains a match to the two orthogonal components of the wave and a differential phase shift between the two orthogonal components slightly in excess of a desired 90 degree orthogonal phase relationship. Upon a differential counter rotation between a first and a second of the polarizer sections, the total phase shift introduced by the polarizer sections is reduced to 90 degrees without significant shift in the match of the two orthogonal components. The equality of the amplitudes of the two orthogonal components is attained by a rotation of the polarizer (42) with respect to the orthomode transducer (34). This provides for a precise generation of a circularly polarized wave. In a satellite communication system, the polarizer system is installed between an ORTHOMODE transducer (34) and a feed (24) of an antenna (22) for operation concurrently with clockwise and counterclockwise circularly polarized waves.
摘要翻译：与至少一个电磁波一起工作以产生圆偏振波的系统（12）包括沿着一个电磁波的传播方向设置的多个偏振器部分（56）。偏振器部分具有相应的一排相移的元件，以杆（76）的形式被调节以提供与波的正交分量匹配。每个偏振部分内的相移元件的穿透和间隔与波的两个正交分量匹配，并且两个正交分量之间的差分相移稍微超过期望的90度正交相位关系。在第一和第二偏振器部分之间的差分反向旋转时，由偏振器部分引入的总相位减小到90度，而两个正交分量的匹配没有显着的偏移。通过偏振器（42）相对于正射模换能器（34）的旋转来获得两个正交分量的振幅的相等性。这提供了精确生成圆偏振波。在卫星通信系统中，偏振器系统安装在ORTHOMODE传感器（34）和天线（22）的馈送（24）之间，用于与顺时针和逆时针圆偏振波同时操作。
