here is my best guess , (sorry if I'm wrong and I'm unsure of the impedence but I'd still use 50 OHM coax... or an antenna straight onto it) but use a multimeter and find an earth point , use the shield from the USB to locate this. This is normally the largest piece of copper and attach the earth braiding as close to the signal point that your going to attach as well - do not bridge the two - the signal point looks like it has a tiny smd capacitor accross it (maybe a resistor?) personally I'd remove this , which would detach the internal antenna (the copper coloured large track) and this would be the centre core for the coax to the antenna.
