Helical antenna design for wireless power transmission: A preliminary study

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 helical antenna design for wireless power transmissions through radio wave frequency of 300 MHz to 400 MHz. The antenna is being designed and simulated using CST microwave software. The parameters highlighted in this paper include return loss, voltage standing wave ratio, and radiation pattern. Preliminary findings indicate that the helical antenna design is suitable for wireless power transmission. Hence, the research has a prospective future of being extended for fabrication and prototype testing.
