Abstract
Abstract A Quick Response (QR) Code style antenna is presented. Such an antenna can provide two-level authentication, both optically through the current QR technology, plus a radio frequency (RF) signature from microstrip patch antenna designed from the QR signature using copper patterning. The antenna is designed through the pixilation of a patch antenna where conductor is present in the dark regions of the optical QR code. The QR based antenna design has a unique frequency and radiation signature and can be used for RF authentication of products. The design process for the pixilation is presented as well as fabrication and measured results of a QR code antenna design. The possibility of using a Genetic Algorithm to create a “library” of acceptable antenna results in accordance with the QR data it represents is also discussed.
