Laptop Wifi Card Advice

So I ordered this wifi card for my Asus 1001p:

Intel Network 62205AN.HMWWB WiFi Link 6205 Half Height Minicard

My question is will I need to buy antennas for it or will it come with them? My netbook only has a single antenna, this card can connect up to two.

Should only need one antenna connection I expect.

I suspected it would, do you think I would notice any benefit from putting in a second one?

The Asus 1001p is the simplest laptop I've ever tried to take apart, I could easily hide one in there somewhere. But it would be a bit of a haste to order one.
