相互隔離之雙模轉換器及其應用
國立清華大學
2014/01/21
本發明提供一種相互隔離之雙模轉換器,其包括TE01模之轉換器包括圓形波導與連接圓形波導周圍之矩形波導;以及TM01模之轉換器包括由同軸之外導體與內導體形成之同軸波導,以及一端與同軸波導之一端連接之圓形波導,其中矩形波導與圓形波導連接之端口之一對稱軸與圓形波導之軸向平行,因此不影響TM01模之傳遞。於一應用中,相互隔離之雙模轉換器可於同一輸出入端輸出TE01模與TM01模,提供能量分佈更為均勻之微波加熱。於另一應用中,將二相互隔離之雙模轉換器對接,而形成隔離度較高且損耗較低之雙通道接頭,可應用於雷達系統或衛星系統之旋轉接頭。 An isolated dual-mode converter includes a TE01 mode converter including a circular waveguide, and rectangular waveguides connected to the circumference of the circular waveguide; and a TM01 mode converter including a coaxial waveguide, formed by coaxial outer and inner conductors, and the circular waveguide connected end-to-end with the coaxial waveguide, wherein a symmetrical axis of the terminal opening of the rectangular waveguides connected to the circular waveguide is parallel to the axis of the circular waveguide, thereby avoiding interfering with the propagation of TM01 mode. In an application, the isolated dual-mode converter outputs TE01 mode and TM01 mode at the same port, thereby achieving more uniform microwave heating. In another application, two isolated dual-mode converters are connected back to back, forming a dual-channel joint with high channel isolation and low transmission loss, which may be used for a rotary joint of a radar or satellite system.
