Detection plate with adjusable transmission and reception range by positioning a movable attenuator.

摘要

The lamina has a chip module (10) comprising a chip (14), and a coupling element connected with the chip. An antenna module (12) comprises an antenna conductor (18), which is coupled with the coupling element and designed in form of rectangular structures. An adjustable damping element is arranged proximity to the coupling element and/or the antenna conductor and utilized for reducing transmission and/or receiving range in relation to a maximum value. A carrier holder is supported on the damping element. The damping element is displaced relatively parallel to a carrier plane (20).
