This document proposes a system to automatically recharge mobile phones through microwave transmission as the phone is being used. The system would transmit microwave signals from an antenna along with voice signals. Mobile phones would require minor additions like a sensor, rectenna, and filter to receive the microwave energy and use it to charge the phone battery. This would eliminate the need for separate chargers and allow the phone to charge as it is being used through voice calls. Manufacturers could remove talk time and battery life from phone specifications as a result.
