According to the pictures linked to in the article, they were 2 SAW devices attached to a board. The total space they took up on the board was about 7mm x 3mm.

Maxwell's equations do describe antennae. Well, to be more accurate, the most current equations do.

(An American antenna expert updated one of the equations around 20 years ago based on his experiments in antenna performance.)

What are you talking about?

Perhaps what throwaway8198 is referring to are the practical consequences of Maxwell's laws as formulated by an American team in the 1960s [1]. For a thorough, more recent study, I highly recommend [2].

Nah, if you read the PRL it's all classical E&M. Maxwell's Equations are Correct.

Of course, interaction of radiation with a material is all about constitutive relations anyways.

Their idea is that Maxwell's limit only applies to conductors, and what they use is dielectric ceramics.
