iphone 3GS signal 3G poor

i've repaired broken path on 3Gs antenna.

The Gsm (Edge) signal is good. But the 3G is very poor (1 bar or no signal at all).
Are there any other antenna path for 3G or only one antenna is used?
i also tried this solution:
iPhone3GS_NoSignal_Fix_Repair_Guide , but signal is lost both gsm and 3G.

please help
