| 摘 要： | 将反射系数最基本的表达式运用到泄漏同轴电缆中，得出周期垂直开槽泄漏同轴电缆的反射系数，提出在每2个槽孔之间开设仿真槽的方法来削弱或抵消原来的反射系数，并更换仿真槽的位置进行仿真分析，可知在不同位置开槽会抑制不同位置的谐振点，从而达到扩展频带的目的，为提高通信质量提供了良好的理论依据．

| Abstract: | The reflectance of the leaky coaxial cables with periodical vertical slots was obtained using the elementary expression of reflectance to leaky coaxial cable. It is suggested to reduce or counteract the original reflectance by adding the simulated slots between each pair of slots and changing their locations. Through the simulation analysis, we found that the simulated slots at different positions can restrain the resonance points at corresponding points, thus extending the fi-equency band. The research provides a theoretical foundation for improving the communication performance. |
