Corrugated leaky coaxial cables

摘要

Low pricing of radio communication systems has extended the use of radio communications. The operating frequency is becoming a microwave hand with improvement in the access speed. LCX (Leaky Coaxial Cable) is used as an antenna for transmission and reception in confined areas such as tunnels or underground. However, the characteristic in demand ranges from several MHz to several GHz. The corrugated LCX (W-LCX Widehand Leaky Coaxial Cable) has holes for radiating electric waves on external conductors of the conventional corrugated coaxial cable. Therefore, it can be expected to have wideband characteristics by radiation of coupled mode. We experimented with a corrugated LCX to clarify many characteristics. Compared to the conventional LCX using radiation mode, the corrugated LCX is applicable to wideband use. Furthermore, it excels also in flexibility and economical efficiency. Applications to various radio communications Systems can be expected.
