地面导线环是变频测深发射天线的一种形式.Wait曾计算了离地面高度为h的小导线环的辐射电阻,但由于所用近似方法的限制,他得出的结果不能用在置于地面的导线环的情况(若令h=0,所给出的辐射电阻将等于∞).在本文中,我们导出了具有有限半径的地面导线环的辐射电阻表达式(准确的以及近似的),并给出了数值计算的结果. Ground wire loops are a form of frequency-variable sounding transmitters that calculate the radiation resistance of a small wire loop at a height h from the ground, but his results can not be used on ground due to the limitations of the approximate method used (If h = 0, the radiation resistance given is equal to ∞.) In this paper, we derive the radiative resistance expression (accurate and approximate) of a ground wire loop with a finite radius, The numerical results are given.
