US Patent 7068225 - Nanoantenna (or is it?)

Perhaps the invention of the previous post may make use of this invention. Although I am a little skeptical of the presented claims after reading the specification. Claim 1 reads:

1. A nano-antenna apparatus, said apparatus comprising: a first conducting surface; a second conducting surface; a gap region between said first conducting surface and said second conducting surface; and at least one discharge switch.

With the exception of the word "nano-antenna" didn't Nikola Tesla (and later Marconi) patent this over a hundred years ago?
Since the specification of this patent gives exemplary sizes of the antenna in the millimeter range and does not teach any specialized manufacturing technique to reduce the size or utility to the nanoscale this patent seems highly questionable.
