New modeling tools?
I'm curious what sort of new antenna modeling and simulation tools have come about within the last few years?

Most antenna modeling software that I am aware of, is based on the principles in NEC, which is now almost 50 years old.  While some recent advances have been made in the user interface, I was not aware of new, significant changes in the modeling itself, since about 25 years ago.

Tape measure antennas
I imagine that the antenna you mentioned used by some CubeSats, got their inspiration from the "tape-measure antennas" that amateur radio operators have been using for decades.  They are handy for making portable VHF Yagi directional antennas, which can be folded up for storage, then easily deployed and carried about when used to locate sources of RF.  Some of their plusses are: cheap and easy to construct, and immensely durable, unlike rigid antenna parts which might break or permanently deform if they hit something.  For CubeSats they make sense because the steel tape measure springs into shape with virtually no plasticity, and no "moving parts" to wear out.
