Problems solved by technology

Thus, since there is not much difference in the positional relationship between the terminal and each of the three antennas, the correlation between the antennas (between the leaky coaxial cables) is high, thereby possibly preventing Fully obtain the characteristics of MIMO

Abstract

A bundled leaky transmission line includes a transmission line inside which a signal is transmitted, wherein multiple leaky transmission lines which exchange a radio wave mainly via a slit provided on an outer circumference of the transmission line are bundled, and the leaky transmission lines are bundled together such that the slit which is provided to each of the leaky transmission lines and which gives radio wave directionality to the leaky transmission line is directed in a direction different from each other.

Description

technical field [0001] The present invention relates to a bundled leaky transmission line, a communication device, and a communication system, and more particularly, to a bundled leaky transmission line that can facilitate proper installation of multiple leaky transmission lines for use as MIMO antennas. Transmission lines, communication devices, and communication systems. Background technique [0002] In recent years, with the spread of wireless local area networks (LANs), communication is performed not only through a wireless area set for a relatively small area such as a standard home, but also for a wide area such as an office or a public building. The need to perform communications in wireless areas has increased. [0003] Measures for covering such a wide area with one access point generally include a method for increasing the radio output of the access point or a terminal performing communication with the access point, and a method for providing a high-gain antenna a...
