Abstract: A main loop is an open loop that is wound on a bar-shaped rod formed of a magnetic body or an insulation body and that has terminals T and T that couple a signal source or a receiving circuit to the main loop. The number of turns is 1 or more. An amplifying loop is wound on a part of the rod that is different from the part on which the main loop is wound. The main loop and the amplifying loop are thus spaced from each other. The amplifying loop is a closed loop including no terminals. The number of turns is 1 or more. The number of turns may be the same as or different from the number of turns of the main loop.

Conversely, at a timing when a negative voltage is applied to the signal terminal of the alternating-current source, a counterclockwise current flows through one loop antenna while a clockwise current flows through the other loop antenna.
