TRANSMISSION LINE, AND BROADCAST SYSTEM

PROBLEM TO BE SOLVED: To provide a transmission line capable of uniformizing a space that can receive radiated radio waves, irrespective of the distance from a start point. SOLUTION: A uniform radiation transmission line is configured in such a way that two electric wires 2 each having a size 2a are arranged side by side on the same plane. The electric wires are arranged so that the distance between the electric wires becomes gradually wider from the start point to an end point to allow a product h×I of a distance h between the electric wires at a certain point and a current I flowing through the point to be constant or substantially constant. With this configuration, the field strength of the radio waves to be radiated is constant or substantially constant irrespective of the distance from the start point, thereby uniformizing the space where radiated radio waves radiated from the uniform radiation transmission line can be received.
