What should I add or remove in increasing the detecting range, see the attachment photo. THANK YOU ! 
Trying to increase the detecting range of cell phone detector to few more meters for observing wide.

what I mean is just i want to have a long distance range for a mobile detector. Because that circuitcan detect only for about half meter.

I am amazed that somebody chose the CA3130 as a detector. Try making a loop antenna and turning it with the two input matching capacitors to the telephone's transmit frequency.
What's wrong with CA3130 Sir? Check this out sir. How is it? what should I do to have a long distance range.

There is noting wrong with the CA3130. It was one of if not the first CMOS opamp from the mid-1970's. Its designers would not have imagined that in the distant future anybody would be using it as a microwave detector.
As I said, it would probably work better with an antenna.
