In advance of actually reading the claims (probably do that tonight), I
think it's quite likely that the claims cover more details of the design
of the amplifier than phased arrays.
Sure, there will be a big claim for "A disposition of two or more
antennas with the signals combined to produce a directive antenna
pattern" which won't hold up, but there will be a claim like:
"A plurality of antennas as in Claim 1, with an amplifier, comprising an
arrangement of electrical components comprising A, B, and C, where the A
component is a capacitor..."
That kind of claim will usually hold up.
