It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don’t like being tethered to the wall. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound Impossible?
A system will be presented using existing antenna and charge pump technology to charge a cellular phone battery without wires.
This report covers the basis and design of the wireless battery charger. The wireless charger will convert the RF/ microwave signal at 915 MHz frequency into a DC signal, and then store the power into a battery.
In this first step, we will use a standard phone, and incorporate the charging technology into a commercially available base station. The base station will contain an antenna tuned to 915MHz and a charge pump. We will discuss the advantages and disadvantages of such a system, and hopefully pave the way for a system incorporated into the phone for charging without the use of a base station.
