[WiFi Antenna Connector]

I have to replace a WiFi card in my laptop and the antenna connectors that I have in my current card are smaller than the ones in this card.

I found in this site that this connector is called U.FL, but I cannot find the connectors online to replace the ones in my current antenna.


Can somebody please tell me where may I find the antenna connectors for this?

You can use any of the ICs listed here.

I've even used an IC that I've ripped from a dead DVD player, I have no idea of its brand nor model, but it works. :)
