技術摘要 / Abstract


一種應用於同軸線至微帶線之轉接的接頭設計及裝配方法,將一同軸接頭串接一內徑及厚度皆經過適當設計的金屬套環而形成一改良式同軸接頭,再以此改良式同軸接頭進行同軸線與微帶線之間的轉接。在轉接裝配時,微帶線的信號線不可伸入金屬套環的穿孔中。由於金屬套環的內徑尺寸與厚度為決定轉接頻率響應之重要參數,因此透過適當地設計金屬套環的內徑及厚度和轉接的裝配方式,可以減弱甚至完全去除源自傳統同軸接頭的第一高階模態在轉接頻率響應之高頻處所引發的共振反應,如此可以改善轉接在高頻處的插入耗損,進而增加此二傳輸線之間轉接的1-dB通帶。A method to design and assemble a connector for the transition between a coaxial cable and a microstrip line involves in connecting a coaxial connector in series with a metallic ring to form a new coaxial connector, wherein the thickness of the metallic ring and the diameter of its through hole are important design parameters to determine the frequency response of the transition. By properly selecting their values and connecting the new coaxial connector to the microstrip line, a resonant response caused by the excitation of the first higher-order mode of the original coaxial connector can be attenuated or even eliminated from the frequency response. Thus, the method improves the insertion loss of the transition at high frequencies, and increases its 1-dB passband. Note that the signal line of the microstrip line is not inserted into the through hole of the metallic ring in the final assembly of the transition.
