【Abstract】 Although the structure of the leaky coaxial cable seems simple, but the calculation of its capacitance and inductance is not so easy. In previous work, we proposed a method that can determine the capacitance of the leaky coaxial cable accurately. While in this paper, a method that can be used to calculate the inductance of the leaky coaxial cable accurately is presented. By using this method, the relationship between the inductance and the slot angle of the leaky coaxial cable can be easily studied. Combining this method with the previous numerical method proposed for capacitance calculation, the relationship between the characteristic impedance and the slot angle of the leaky coaxial cable is ready to be obtained.更多还原
