在移动通讯系统中,用来导引电波的漏泄同轴电缆是一种良好的通讯媒质,它能弥补无线通讯系统的缺陷。因此,对它在各方面的实际应用可能性作了研究。我们研究了漏泄同轴电缆的主要特性,证实了它与实验结果的一致性。进而明确了通过变更槽缝的布置,就可在相当宽的频带内获得均匀的辐射场。漏泄同轴电缆不仅在铁路通讯系统而且在公路通讯系统以及移动体的监视,遥测系统中都可广泛地应用。其中,我们还考虑了把漏泄同轴电缆用至无线电话系统中,确认了它在辐射场方面要比普通的天线更为理想。
In the mobile communication system, the leaky coaxial cable used to guide the radio wave is a good communication medium, which can make up for the shortcomings of the wireless communication system. Therefore, it is studied in various aspects of the practical application possibilities. We studied the main features of the leaky coaxial cable, confirming its consistency with the experimental results. It is then clear that by changing the slot arrangement, a fairly wide band of radiation can be obtained. Leakage coaxial cables are widely used not only in railway communication systems but also in monitoring and telemetry systems of road communication systems and moving bodies. Among them, we also considered the use of leaky coaxial cable into the radiotelephone system, confirming that it is more desirable than a normal antenna in the radiation field.
