Transponder for use in fluid reservoir, has antenna formed of conducting loops, whose biggest expansion corresponds to half of wavelength of electromagnetic field of work and main axis is designed parallel to assembly subsurface

摘要

The transponder has an identification chip (13) and an antenna, where the antenna is formed of conducting loops (11), whose biggest expansion corresponds to multiple of half of wavelength of electromagnetic field of work, and main axis is designed parallel to an assembly subsurface (12) and whose level is designed perpendicular to the assembly subsurface. The conducting loops possess the form of very slim rectangle and its longest expansion is arranged parallel to the surface level of the assembly subsurface.
