Don't ever give up! It just might come true.

Thanks for Your Encouragement sir..i am continuously trying to solve this. May i got.

Today I noticed one situation while doing experiments for my project. as i moved far away from my transmitter voltage between Antenna and Ground was changing. means it was 318mv, when it was nearer to rf transmitter. then it was 270mv when we go away, when we moved more far away 150mv we got, means antenna  to ground voltage level was decreasing as i go far way.

Now how  i can indicate this millivolt change by glowing LEDs.  it may need some amplification. how i do it?

Sounds like something is acting as a detector and rectifying the antenna signal.  That won't be useful
at long range as the voltages drop below the forward voltage of practical passive rectifiers.
