#CMT# #/CMT# The inductor has conductors (100 - 109), parallel, mutually equidistant and distributed over a surface (120). The conductors are connected with each other by connection conductors (130) to form strands of an electric circuit. Ends of the strands are connected to an electric power supply (140) that circulates an electric current in the conductors. The conductors are incorporated in a plane non conductive base (150) on which articles (160) are placed. The articles have electronic tags (170) whose antenna is in a plane forming an angle less than or equal to 45 degrees with the conductors` axis. #CMT# : #/CMT# An independent claim is also included for a device chosen among a support, a vane, a cash register and a base station and comprising an indicator. #CMT#USE : #/CMT# Used for forming an antenna of a device such as a support, a vane, a cash register of a store and a base station (claimed), that is used for reading an electronic tag such as transponder and radiofrequency identification (RFID) tag, of a product. #CMT#ADVANTAGE : #/CMT# The former set of conductors are arranged such that a magnetic field can be generated perpendicular to them and parallel to the surface containing them, thus allowing to read the electronic tag in an easy manner, irrespective of the direction of antenna of the tag. The inductor allows to reduce the inductance with respect to an 8 configuration antenna, thus permitting to reduce the voltage at terminals of an antenna. The electric supply can be performed in a simple and easy manner, and hence a transmitter can be manufactured with a small size. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of an inductor. 100 - 109 : Conductors 120 : Surface 130 : Connection conductors 140 : Electric power supply 150 : Plane non conductive base 160 : Articles 170 : Electronic tags. |
