It may already have one.
As for no gain, I assume that you mean they provide 0dBi, which is true.
However quick question: how many mW in 0 dBm, 1dBm and 2dBm?
Now remember that ye olde standard rubber duckie on that AP you got at Fry's (or even from Cisco) has a 2.15dBi antenna on it. This is
about 65% more EIRP than a 0dBi antenna, but, in the great scheme of things, not all that much.

PCB antennas are generally inefficient, and provide for no gain. Here's
an
interesting application note that illustrates what you can expect from a
PCB
antenna for WLAN service:
