Title:
LOOP ANTENNA
Document Type and Number:
WIPO Patent Application WO/2017/126151
Kind Code:
A1
Abstract:
A main loop 1 is a closed loop that is wound around a rod 3 formed from a magnetic or insulative body, and has terminals T, T for connecting a signal source 5 or a receiving circuit (not depicted). The winding number thereof is 1 or more, and is, for example, 5. Fig. 1 is a figure depicting the connection of the signal source 5 as an example. In addition, an amplification loop 2 is wound around a section of the rod 3 other than the section thereof around which the main loop 1 is wound. As a result, the main loop 1 and the amplification loop 2 are separated from one another. The amplification loop 2 forms a closed loop and is not provided with a terminal. The winding number thereof is 1 or more, and is, for example, 5. The winding number thereof may be the same as or different from the winding number of the main loop 1.
