QR code antenna for wireless and security applications
2013
This paper presents the first QR code antenna. The QR code itself represents a specific code based on any text, URL, and any alphanumeric contents. However it can also serve as the antenna that is described in this paper, or any other QR code-shaped antenna. This antenna has a return loss of 8.5 dB at 2.43 GHz and gain of 1.25 dBi, representative of a good receiver. These antennas can be used as an additional security feature and/or replacement for RFID tag antennas.
