Product identification using barcodes has gained good astounding, especially at the point of sale, where different products are being scanned individually before making the payment receipt. These products when at the warehouse meets issues like individual scanning demands significant time and labor to be involved in the human error. Barcodes have been in a process of replacement by Radio Frequency Identification (RFID). RFID is a technology that enables data transfer wirelessly and provides several advantages over barcodes which mandatory requires line of sight. Much of the work has been done on RFID tag antenna design, but efficient reader antenna design has been a major need of the hour for big warehouses, that came across bulk data to manage on daily basis. RFID reader antennas are unable to focus their RF energy on a desired zone. This paper proposes a novel multi-linear polarized RFID reader antenna design that utilizes the RF energy efficiently to meet the bulk reading application that will help in managing the tagged stock for industrial application.
