摘要利用市售偶极子天线加S-参数适配器,完成了一套可计算偶极子天线;在30 MHz~1 GHz内,在不同频点、不同高度(2 m、3.5 m)和不同距离（10 m、1.2 m）条件下,该套偶极子天线场地衰减/插入损耗的仿真结果和实测结果的差别小于0.9 dB;相应地,天线系数的仿真结果和实测结果的差别小于0.45 dB。由于仿真结果提供了一种独立的、更为准确的参考值,因此以可计算偶极子天线为基础,可解决在天线系数校准中出现的天线系数与校准场地之间量值循环问题。这种方案借助于S-参数适配器,可把现有的一些偶极子天线转换为可计算偶极子天线。

Abstract：A set of calculable dipole antennas are developed from 30MHz to 1GHz, based on a set of commercially available precise dipole antennas and a set of specific S-parameters adaptors. The site insertion loss /site attenuation difference between simulating results and measurements is less than 0.9dB for different antenna heights, separations and frequencies. The antenna factor difference is less than 0.45dB accordingly. Because independent and more precise value can be computed from calculable dipole antennas, they are vital to solve the circular dilemma between OATS and antennas. The advantage of this solution is that calculable dipole antennas can be acquired based on some commercially available dipole antennas.
