摘要
本文提出了用边界元法分析喇天线的方法,并对其入口驻波特性、口径场、近区场和辐射场作了深入的探讨,得到的数据均与其它方法的结果相吻合。由于本文方法具有推导简单,计算省时的特点,所以是研究喇叭天线的一种有效途径。
The boundary-element method is used for the investigation of horn antennas, and the input standing-wave property, aperture field, near field and far field of horn antennas are studied throughly. The obtained results are in good agreement with data available in the literatures. Some examples are given to show the validity and usefulness of this approach.
