An RFID antenna and amplification system whereby aluminum shaving or ceramic powder resin strips form a part of product shelving. The strips are embedded into or added unto or attached to the shelving through a process of extrusion and adhesion. The shelving can be located in a warehouse, distribution center, or retail environment (hereinafter the "environment"). The embedded or added on or attached strips act as a super antenna for gathering a remote source magneto-electric signal interrogation. The remote source is contemplated to be a cellular telephone transmission tower radiating microwave electromagnetic signals. The super antenna gathers the interrogating microwave frequency electromagnetic signal and sends this signal through a wired or wireless connection to a transformer located in the environment, on or near the product shelving. The transformer then modulates the microwave inquiry to the resonant frequency of the RFID tags attached to or embedded in articles located on shelves in the environment. The transformer is an integral part of an interrogator which reads individual RFID tags at an item level using the RFID industry standard "backscatter" methodology. The tag interrogation is conducted at an amplified and consistent power setting, fewer than two watts, to maximize the read rate of the RFID tags. The transformer is powered by a wall socket. The same power source is connected back to the original super antenna. The transformer communicates the harvested RFID tag data to the super antenna. The super antenna then responds to the initial interrogation by the remote source via active microwave electromagnetic signal.
