Hallo ,I am building a mobile phone detector. But I noticed that the range of detecting signal is too short. So, I want to extend the range of detection.here is the schematic which I used:

 

This kind of circuit is not going to give you much range whatever you do to it.

Can you give another circuit or a new idea?

 

To receive such signals - very wide bandwidth microwaves - with great sensitivity would be difficult even for someone who knows what they are doing with such circuits. That isn't me.
