Context:
Jonathan Raiman's final Electronics 128 project, at Pomona College, CA, in the spring of 2011.
Thesis presentation from 2013 on the same topic: http://physics-thesis.herokuapp.com/
Synopsis:
Using resonant inductance (a large air core transformer basically) to send a few Watts over 2/3 of the antenna's width. The amplifier's is badly impedance-matched to the antenna, so unfortunately for now the majority of the power is converted to heat.
