振子型电小天线近区辐射场强的快速预测

一般大型移动平台（如：舰船、飞机等）上都布置有多台短波，中波电台，同时伴有大量武器装备，研究用于平台EMC预测的电台天线近区辐射场电场强度的快速预测公式。从电偶极子和短振子线近区辐射场公式出发，经过理论推导，得到了振子型电小天线近区辐射场电场强度的快速预测公式，该公式可方便快捷地计算出振子型电小天线近区的辐射场强值，其公式计算结果与MOM数值计算结果基本一致。

Fast Prediction of Near Field Strength Radiated by Small Antennas

Large sized moving-equipments (e.g. warships, airplanes, etc.) are normally equipped with many radio communication stations and weapons, formulas are often required for the fast estimation of the field strength radiated by the antennas of such radio communication system on nearby areas for EMC analysis and prediction. Through analysis and transformation of formulas on the basis of near field formulas for the small antennas (electrical dipole and short-element antenna), formulas for the fast estimation of the electric field strength radiated from small antennas on the nearby areas of the antenna are derived. They are handy for use and the calculated results are in good agreement with results calculated with the MOM method.
