| 摘 要： | 给出一种用于分析同轴开槽天线的有效方法。利用这种方法，设计并实现了用于低轨道卫星移动通信（LEO－MSAT）的含有5个周向缝的同轴开槽天线。计算的理论方向性图和实验结果吻合良好，这表明给出的方法是正确的。实验和理论分析结果表明，通过合理地安排槽的位置，可以实现LEO－MSAT应用所需的方向性图。

| Abstract: | An improved method is proposed for the evaluation of multislot coaxial line antennas. Based on this method, a multislot coaxial antenna is designed and implemented. The theoretical radiation pattern is in good agreement with the experimental one, indicating that this method is valid. The experiment and the theoretical analysis show that the radiation pattern of the designed antenna is like an upward skewed donut, which is desired for LEO_MSAT applications and can be achieved by strategically arranging the positions of the circumferential slots cut on a coaxial line protruded from a ground plane. |
