Abstract

In this paper, we introduce a wideband antenna array for RF energy harvesting from 3G/4G and Wi-Fi. The array consists of four parallelly linked wideband antenna elements and a metallic reflector to enhance gain and suppress back lobe radiation. In measurement, the antenna array possesses a wide bandwidth spanning from 1.6 GHz to 2.5 GHz, fully cover the three harvested bands, and the high gains between 13.5 dBi and 14 dBi. The antenna is employed in a multiband rectenna for energy harvesting and placed in the ambience. The rectenna was able to collect up to 0.27 mW power.
