1. A wireless tag unit containing an antenna having a semiconductor element including communication and memory functions, and a wireless tag including a dielectric layer and a metal layer structured to be opposed with the antenna via the dielectric layer, the wireless tag unit comprising:
a first conductive element electro-magnetically coupled with the metal surface; and a second conductive element electro-magnetically coupled with the first conductive material, the second conductive element being structured to be branched from the first conductive element, wherein a part of the second conductive element is structured above the antenna so as to keep a predetermined distance from the first conductive element, an open structure being provided with said a part of the second conductive element not to fully shield an area above the antenna. |
