Just for grins, look into this link, from Ohio State University from back in 2011!

There are also articles more recently (2018) on electronics in one’s clothes, and computers in one’s clothes in this website’s news as well.

A small remotely tuned loop (say 12” diameter) would seem to be the best choice, as it would fit entirely inside a small backpack. It could have  modest efficiency while not requiring a counterpoise wire. Rigid 1” copper pipe formed in a square would be convenient to deploy.
