摘要: 本文分析了介質(zhì)鏡象線(xiàn)的波阻抗與幾何尺寸和頻率的關(guān)系;研究了阻抗匹配的必要性和可能性;提出了一種選優(yōu)的匹配器。對(duì)于阻抗比為4.7的兩截介質(zhì)鏡象線(xiàn),得到駐波系數(shù)S1.10的帶寬達(dá)10.5 GHz的寬帶特性。選優(yōu)匹配器的性能優(yōu)于用經(jīng)典方法設(shè)計(jì)的匹配器。

Abstract: In this paper the wave impedaa.ee of dielectrie image line as a function of geometry dimensions and frequency is analyzed. Both the necessity and the possihility of impedance matching are studied. An optimal matching element is put forward. Its bandwidth with VSWR1.10 can be as wide as10.5 GHz, when it is connected between two dielectrie image lines with an impedance ratio of 4.7. Its properties are obviously better than those of elassical type. -
