本节将讨论EMC天线的使用和应用以及天线因素。讨论了天线增益、天线系数、功率密度（W/m2）和场强（V/m）之间的关系。文中给出了一些使用实例。还提供了用于EMI测量的商用EMC天线的图示。除图示外，还列出了天线系数、频率范围、典型用途（应用）以及这些天线的制造商。

This AIR discusses the use and application of EMC antennas and antenna factors. The relationships between antenna gain, antenna factor, power density (W/m2), and field strength (V/m) are discussed. Some examples of their use are given. Illustrations of commercially available EMC antennas commonly used in performing EMI measurements are included. In addition to the illustrations, the antenna factors, frequency ranges, typical uses (applications), and the manufacturers of these antennas are also listed.
