A wireless sensing technique based on channel estimation in leaky coaxial cable antenna system

摘要

This paper describes on wireless sensing techniques on the LCX (leaky coaxial cable) antenna system. Recently, LCX antenna has been developed for the use of GHz such as 2.4 GHz ISM band [1], and its diameter of dielectric is reduced to about 5mm. By virtue of the capability of flexible arrangement and of wide coverage of these slim cable antenna, they can be applied to wireless sensing infrastructure. This paper introduces various sensing applications using LCX antenna such as intruder sensor, linear cell MIMO system and position location.
