Leaky coaxial cable (LCX) is widely used for wireless communication systems as an antenna for a linear-cell, which covers long and shallow areas. Since one LCX is usually utilized as one antenna, more than one LCX is required to configure a multi-input multi-output (MIMO) system. It means it is costly and space-consuming. To resolve these problems, we proposed a novel MIMO method for LCX. In this...
In linear service areas such as a tunnel and along railways, leaky coaxial cable (LCX) is widely used as antenna for radio communication. Usually, one LCX is utilized as one antenna. Therefore it requires more than one LCX to configure an multi-input multi-output (MIMO) system. We have recently proposed a method that one single LCX can be utilized as two antennas by feeding different RF transmit signals...
Leaky coaxial cables (LCX) have been widely used as antennas to form linear service areas for radio communication systems. Such services of linear cells have been deployed inside tunnels, along railways, and so on. Usually, one LCX is utilized as one antenna. Therefore it requires more than one LCX to configure an multi-input multi-output (MIMO) system. In this paper, we propose a MIMO system using...
In this paper, the path loss in the automotive engine compartment is characterized in a frequency range from 2 GHz to 20 GHz for the development of a future wireless-harness communication enabling wireless interconnections between modules and sensors. As an important factor of the propagation, the path-loss exponent is extracted from measured frequency characteristics of the path loss. The key findings...
We have been developing a 2.4 GHz point-to-multipoint wireless communication system suitable for use inside mechatronics ICT (Information and Communication Technology) equipment to replace wire harnesses inside equipment with wireless communication as a useful technique of weight reduction and simplification of system assembling [1]. One of the critical problems of such applications is that antennas...
