Wiley, N.J., 2006): 1865: James Clerk Maxwell published his work on the unification of electric and magnetic phenomenon, including the introduction of the displacement current and the theoretical prediction of EM wave propagation. 1872: Mahlon Loomis, a dentist, was issued US Patent 129,971 for “aerial telegraphy by employing an ‘aerial’ used to radiate or receive pulsations caused by producing a disturbance in the electrical equilibrium of the atmosphere”. This sounds a lot like radio, but in fact Loomis was not using an RF source, instead relying on static electricity in the atmosphere. Strictly speaking this method does not involve a propagating EM wave. It was not a practical system.

This method relied on the inductive coupling between the two coils, and did not involve a propagating EM wave.

1897: Marconi was issued a British Patent 12,0 39 for wireless telegraphy. 1901: Marconi achieved the first trans-Atlantic wireless transmission. 1943: The US Supreme Court invalidated Marconi’s 1904 US patent on tuning using resonant circuits as being superseded by prior art of Tesla, Lodge, and Braun.
