泄漏同轴电缆耦合损耗影响因素

Factors affecting the coupling loss of leaky coaxial cable

通过对泄漏同轴电缆外导体开缝处电场的柱面傅里叶变换,求出了标准半波长偶极天线接收的开缝辐射场,然后得到了天线的接收功率.由耦合损耗的定义求得不同的缝隙角度、缝隙周期和频率时的耦合损耗,分别讨论了各因素对耦合损耗的影响,为设计不同耦合损耗的泄漏同轴电缆提供了理论依据.

The field radiated from the slots on the outer conductor of leaky coaxial cable(LCX),which was received by the standard half-wavelength antenna,was calculated by the cylinder Fourier transformation of the electric field in the slots.Then the receiving power of the antenna was obtained,and the coupling loss with different slot angles,slot periods and frequencies was computed in terms of the definition of coupling loss.The influence of these factors on the coupling loss was discussed respectively.This study p...
