【摘要】 本文对研制的正交极化隔离器进行了理论分析。考虑了对高次模和反射波的抑制后,我们设计了一极化隔离器。测试结果表明:对两个波段的频率f₁和f₂（f₁>f₂）,驻波系数小于1.2的带宽分别为2％和5％;插入损耗小于0.5dB。它可以作为频率复用或极化复用天线的一个实施方案。根据这种分析方法,提出在毫米波波段有条件地使用厘米波段的波导作馈线的可能性。更多还原

【Abstract】 This paper deals with the theoretical analysis of an orthogonal polarized isolator.A new kind of isolator was designed in which the high-order mode and reflected waveswere suppressed. The experimental results show that the isolator’s bandwidths for bothbands f₁ and f₂ （f₁>f₂） are respectively 2% and 5% with VSWR<1. 2. Its inser-tion loss is less than 0. 5 dB. This design suggests a practical arrangement for dual-frequency antenna. This method of theoretical analysis provides a possibility of usinga centimeter-wave guides in the millimeter-wave band under certain conditious.更多还原
