Drone Antenna and Fractal Antenna
« on: April 23, 2012, 01:22:36 AM »
This concept of the drone antenna array for intergalactic radio telecommunication I thought of for the past few days. I am not experienced in engineering.

The spires are an interesting feature of the drone(s). They could be elements of a circular phased array antenna or a direction finding array (Wullenweber array) or both. It is hard to tell, but the curvature might be related to a trig function (cosine or tangent).

Esteemed DRT member Nekitamo already did the measurement and math.  He concluded there exists a "linear potential gradient".

Nano scale antennas used for communications, radar and radio astronomy. Developed by MIT.
