When I checked the product page on the Intel site, it said the mini-pci
design in question, is compatible with two or three antenna systems.
It could be, that whatever software/firmware controls the device,
can be configured to not use the third antenna.
http://www.intel.com/network/connectivity/products/wireless/wireless_n/techdocs.htm
From product brief -
"On-board diversity support for systems designed with two or three antennas"
For Wireless_N, there are various options for how the antennas can be
handled. For example, according to the naming conventions here, your card
might have options for 2x3:2 or 2x2:2. Meaning the third antenna connector
might be receive only, for example. (If it was my card, I might try
tracing down the chip numbers on the card, and see if there are specs
that identify how many radios the thing has and so on.)

The fact that you're running at 54, suggests it isn't even in "N" mode
right now. The user guide from the Intel site, lists this.
