Design and Develompent of wireless charging circuit using frequency to charge the Cell phone


We have designed and developed a frequency conversion circuit to charge the cell phone. By using this circuit, anyone can charge wireless-ly. Now I describe about our circuit:::

For the input frequency, i have been used 5MHz with respect to 2mV (AC) current. After completion my circuit, the output has been found 5.91V (DC) with respect to more than 400mA current. So for a mobile charging, minimum voltage need to charge 4.1V and current 400mA. But our designed circuit output is 5.91V and more than or equal 400mA. So it is works in our laboratory. But in real world the frequency for

Downlink (Base station to Mobile) = (935-960) MHz and voltage is 2.69(AC)

Uplink (Mobile to base station) = (890-915) MHz and voltage is 2.01(AC)

So, if this is true, then we are truly determined to say that, our circuit will be works in the real world which will be attached with the cell phone. So no need to use external power source for charging. Talk and charge using frequency till your death.. What about you’re thinking about my circuit...
