‘Bi-loop’ RFID reader antenna for tracking fast moving tags

In the recent past the use of RFID systems has emerged dramatically such that now the world is bringing down the technologies to universal standards. Still there exist many problems related with RFID, which has to be solved out if they are to be used in real life applications successfully. In this paper it discusses the problem of tracking fast moving tags for the RFID systems operate in the HF range. Authors found very little level of research work in the literature focusing this problem. Here the approach is made, by introducing a new antenna structure, named as dasiabi-looppsila, which enhances the performance of RFID systems in the environments of fast moving tags. Other than to this, the new antenna structure adds many advantages such as limited far field radiation, efficient power consumption and easy antenna matching.
