Yes. 802.11b devices include the antenna as they are seen as a
system. Certification is for the whole system as antennas can
change things like EIRP and out-of-band emission level by how
broadband the antenna is. There are exceptions for this rule under
the very vaguely defined "professional install" "out".
You can see details of where the FCC defines this and a discussion
on it on page 4 of my paper at:

"A mass in movement resists change of direction. So does the world
oppose a new idea. It takes time to make up the minds to its value
and importance. Ignorance, prejudice and inertia of the old retard
its early progress. It is discredited by insincere exponents and
selfish exploiters. It is attacked and condemned by its enemies.
Eventually, though, all barriers are thrown down, and it spreads
like fire. This will also prove true of the wireless art."
