DIY Flexible Fractal Window HDTV Antenna

Anonymous Coward writes | more than 2 years ago

An anonymous reader writes "I was intrigued by the new flexible DTV antennas coming out. My old flat, rigid antenna worked well when placed in a window but it was hard to keep it there and it blocked light. I had success with other DIY antennas so I attempted to build my own flexible, transparent DTV antenna out of paper, plastic and aluminum foil using a fractal antenna pattern. It works very well in the UHF range."

This is the best one I've seen so far. It's an 8-element antenna with half of the elements having another iteration of the Koch snowflake.

The post is more about the process used to make the antenna rather than the design of the antenna elements. Part of the reason I did it was to cheaply try different designs. You can make one using Roy's design.

Actually, I think that the foil design is pretty cool. It should be possible to combine the two. For crossovers, just stick a piece of tape in between the layers. Also, it would be interesting to try making it work with a laminator. This really needs to be submitted to hackaday and makezine too, it'll fit right in.
