Highly Miniaturized 1-4 On-Chip Power Divider/Combiner Circuit on Silicon Substrate for Application to Long Distance Wireless Power Transmission

In this paper, for application to a long distance wireless power transmission, a highly miniaturized 1-4 power divider/combiner employing periodic structure was fabricated on semi conducting silicon substrate. The 1-4 divider/combiner showed good RF performances from 1 to 25 GHz, and its size was 1.08 x 0.63 mm2, which is 0.14 % of the size of the one fabricated on PCB. Wireless energy or power transfer is the transmission of electrical energy from a power source to a power consumer without interconnecting wires
