Abstract:
PROBLEM TO BE SOLVED: To eliminate the necessity of a long-term verification experiment and operation stop at a site to be followed.SOLUTION: In a communication system, a base station and a communication terminal, both of which use a leakage transmission line as an antenna, wirelessly communicate with each other. The communication system comprises the base station comprising a first leakage transmission line forming a line segment and the communication terminal comprising a second leakage transmission line forming a line segment. In a plane including the entire first leakage transmission line and at least part of the second leakage transmission line, the angle of inclination between the second leakage transmission line and first leakage transmission line is at -5 degrees or above and at 5 degrees or below. The torsional angle of the second leakage transmission line to the direction vertical to the plane is at -5 degrees or above and at 5 degrees or below. The length of the second leakage transmission line is at 5 m or below.
