摘要： PROBLEM TO BE SOLVED: To provide a waveguide type polarizer/demultiplexer which can be miniaturized, made axially short and can have a broad band, and has excellent performance.
SOLUTION: Since the distance between upper and lower sidewalls of third and fourth rectangular branch waveguides 2c, 2d is half or lower than the free space wavelength of a used frequency band, a horizontal polarized wave H hardly leaks toward terminals P4, P5 by an insulation effect. The direction of an electric field is changed by a metallic block 4 and a short circuit plate 3, the field becomes an electric field distribution in a state in which E face miter-shaped bends of the two waveguides are placed symmetrically. Accordingly, the radio wave H inputted from a terminal P1 is efficiently outputted to terminals P2, P3 while suppressing the reflection to the terminal P1 and the leakage to terminals P4, P5. Furthermore, a square waveguide step 5 is provided in a position where a reflected wave from a branching section and a reflected wave by the step 5 are cancelled each other in the vicinity of a cutoff frequency of a TE01 mode of the radio wave H, thereby suppressing the deterioration in reflection characteristics of the radio wave H, The same is true for a vertical polarized wave V.

摘要翻译：要解决的问题：提供一种波导型偏振器/解复用器，其可以小型化，轴向短并且可以具有宽带，并且具有优异的性能。解决方案：由于第三和第四矩形分支波导2c，2d的上侧壁和下侧壁之间的距离为使用频带的自由空间波长的一半或更低，因此水平极化波H几乎不会朝向端子P4，P5泄漏通过绝缘效果。通过金属块4和短路板3改变电场的方向，在两个波导的E面斜面弯曲的对称状态下，场变为电场分布。因此，从端子P1输入的无线电波H被有效地输出到端子P2，P3，同时抑制对端子P1的反射和对端子P4，P5的泄漏。此外，在波分复用部分的反射波和台阶5的反射波在无线电波H的TE01模式的截止频率附近被抵消的位置处设置方波导步骤5，由此抑制无线电波H的反射特性的劣化。垂直偏振波V也是如此。（C）2004，JPO
