I am now using an atheros AR5007EG adapter on this laptop.I would like to upgrade this to an Intel 5100 wifi link. The 4315 only has one antenna ,But for Intel 5100 it is necessary to attach 2 antennas because it is 1T2R.Is it possible to add another antenna to this laptop?(How?)
Thank you.

You're going to have terrible signal quality with one antenna (you probably have now) so you should upgrade.
Installing an additional antenna will require you to dismantle notebook- not a very hard thing to to but not an easy fix either.
As for the choice of the card itself- 5100 has been known to cause a lot of issues and is not that much cheaper than Intel 5300 which in turn is one of the best wireless adapters available so I'd recommend buying a 5300 (you can safely ignore a third antenna as it's not needed unless you want to connect at 450mbps and have the hardware to do so) -
And what happens with only one antenna connected to MAIN connector ?Would it work like a 1T1R (150/150) and the second 150 link would be ignored? (AUX connector is for receiving only.Right?)

I doubt it will get to 150mbps although it's possible in theory.
The problem is basically every card made since 2005 or so requires two antennas for proper reception.
We've done a test here a while ago and it turns out that while upgrading from two to three antennas doesn't do anything to signal quality, using only one seriously lowers SNR meaning reduced range and throughput are almost guaranteed.
