Circular polarized square patch antenna array for wireless power transmission

Wireless power transmission is a process that takes place in any system where electrical energy is transmitted from a power source to an electrical load without a wired connection. Wireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. Antenna has become the most vital element in any RF system due to its capability as a radio wave transceiver. A properly designed antenna is desirable to ensure efficient transfer of energy. This paper proposes a square patch antenna array 3×3 designed with a circular polarization using slots for wireless power transmission, through radio wave frequency of 2.45GHz. The array is being designed and simulated by using CST microwave software.
