QR code antennas for WiFi/WLAN/Bluetooth applications

Abstract

This paper demonstrates the suitability and successful implementation of QR (Quick Response) code structures as antennas for wireless communication applications. QR code antennas can have different visual shape for the same URL, based on different error correction level. These antennas can be engineered to radiate at the same frequency. Here, the simulations of three QR code antennas are presented. The antennas have low return loss at 2.4 GHz and omnidirectional pattern, ideal for receivers. These antennas can also be used as an advanced and hard-to-replicate security feature for WiFi/WLAN/Bluetooth applications or other.
