Hi friends,
I wish build a RF circuit to block a wide range of frequencies, basically :
Somebody could give some sugestion about how to do that ?
It is not problem, if will be needed to use many antenas at same case.
The range in wich will be used is about 4m.

I wish build a RF circuit to block a wide range of frequencies, basically :
400- 800 Mhz ( RF ID )
801mhz 890MHz ( Bluetooth, ZigBee, Wimax)
900-1100MHz ( GSM CDMA)
1100MHz- 1800MHz ( GPS receiver )
1800MHz-2000MHz (1G )
2000-2400MHz ( 2G )
2450-2500MHz ( 3G )
2.5GHz-2.7GHz ( 3.5 / 4G )
Somebody could give some sugestion about how to do that ?
