Embodiment Construction

[0022] According to the embodiment shown in the drawings, a plurality of transponders, 2a, are arranged on a plate-like or strip-shaped common support 1, and each transponder is distributed front-to-back and / or adjacent to each other.

[0023] A UHF antenna element 3 with a shielding shell 4 is arranged below the planar support 1 . The shielding case 4 is designed for shielding UHF waves. The shielding case 4 surrounds the antenna element 3 such that the opening 5 on the top surface of the shielding case 4 faces the underside of the support 1 . The opening 5 allows the measurement area of ​​the antenna element 3 to be aimed in the direction of the selected transponder 2a without affecting other transponders adjacent to the selected transponder 2a.

[0024] The shielding shell 4 is movable in the x-direction and the y-direction in a plane parallel to said supporting surface, as indicated by arrows 6 and 7 . In this way, the antenna element can be driven to aim at each success...

Abstract

The invention relates to an ultrahigh-frequency testing device for transponders that are two-dimensionally disposed behind and/or next to each other on or in an area of a joint support. Said testing device is used for checking ultrahigh-frequency functions and other transponder (2) data by means of at least one ultrahigh-frequency antenna element (3). Said antenna element (3) is located within a shielding housing (4) which acts in an isolating manner on ultrahigh-frequency waves and is provided with an opening (5) that faces a selected transponder (2) which is to be checked. Said opening (5) has an area that is adapted to the basal surface of the transponder (2).

Description

technical field [0001] According to the preamble of claim 1, the present invention relates to a UHF detection device for transponders arranged one behind the other and / or adjacent to each other in a mesh-like manner. On the surface of the common support and / or in the common support, the detection device is used to detect the UHF function of the transponder and other data by means of at least one UHF antenna element. Background technique [0002] Transponders based on RFID (Radio Frequency Identification) operating in the Ultra High Frequency (UHF) range are usually mass-produced in the form of web structures (web). The network structure comprises a large number of transponders arranged one behind the other and adjacent to each other on a common planar support. These transponders typically operate at very high frequencies, as well as in higher frequency ranges. [0003] During manufacture, in order to test the function of the transponders arranged in this way, the antenna e...
