Research Brief
The leaky coaxial cable antenna radiates electromagnetic waves to the space along the cable. Since a cable has typically two ports for feeding, simultaneous feeding to each port enables us to use as two antennas. Straight and long radio coverage can be formed by feeding to LCX, that is called as Liner cell. In this study, higher throughput performance has experimentally demonstrated in linear cell than regular omnidirectional transmitting antennas. Moreover, this study shows the scheme of beam steering using two LCXs. Arranging two LCXs in close together, waves from slots are interfered each other. The antenna directivity is investigated by means of electromagnetic simulations.
