We recently did some antenna pattern measurements and included the Pringles cantenna (which I blogged about a few weeks ago) amongst a couple of other great antennas. I doubt if this has ever been done before! The Pringles cantenna performed surprisingly well seeing that we did nothing to improve the conductivity of the can.

We also built a replica of the Pringle version out of copper as show in the image below. The graphs below compare measured S11 and gain patterns between these two antennas.
