準(zhǔn)光腔單微帶貼片輸入阻抗的理論分析
AN ANALYSIS ON INPUT IMPEDANCE OF A SINGLE MICROSTRIP PATCH IN THE QUASI-OPTICAL CAVITY
-
摘要: 本文利用并矢格林函數(shù)獲得了準(zhǔn)光腔中的電磁場積分方程。利用矩量法導(dǎo)出了被一個軸向電流源激勵的單微帶貼片腔的輸入阻抗的計算公式。利用本方法對矩形微帶貼片的輸入阻抗進行了討論。其結(jié)果與微帶天線很類似。這對設(shè)計微帶型準(zhǔn)光振蕩器有重要的參考價值。

Abstract: The electromagnetic field integral equation in the quasi-optical cavity is obtained using the dyadic Green s function. An expression is derived for the input impedance of a single microstrip patch cavity excited by a coaxial probe using method of moment. The input impedance of a rectangular microstrip patch is discussed by this method. The result of this paper is similar to that of the microstrip antenna. There is very important value for designing microstrip quasi-optical oscillator. -
