Shahidali, as you seem to want to build one yourself instead of buying ready made devices, the final result and performance will very much depend on your build quality and the quality of components you use and the antenna you employ at both the transmitter and receiver and also the frequency you end up operating on. Since the inductor will be constructed by you, I emphasise build quality. So, why not try building some of the many circuits you now have acquired (including some you've found yourself), then come back and tell us how you've done and how well they have performed. However, without some good test equipment, or alternatively at least a tuneable receiver in the frequency band of your transmitter, you will have a hard time achieving a measure of success whilst working in the dark, as you won't even know what transmit frequency your construction has ended up with.
