However, there is a disadvantage in that the network configuration for beamforming is complicated. The ESPAR antenna has the advantage of being able to perform beamforming without such a complicated circuit configuration. When the ESPAR antenna is applied to an WPT system, a low-complexity and high-efficient WPT system can be designed. Through the simulations, it is confirmed that the ESPAR antenna can support a wide range forward through 3D beamforming.
