Abstract:
To magnetically couple an annular antenna of a transponder module arranged in a tire, with a transponder while separating mechanically.
A loop antenna 32 is arranged so as to project through a through-hole of an annular body of the transponder module 34 and kept in a non-contact and mechanically inconnected state to the annular body. The loop antenna 32 is magnetically coupled with the annular body. The transponder module 34 is coupled with the loop antenna 32 through the annular body.
