Miniature High Gain Slot-Fed Rectangular Dielectric Resonator Antenna For IoT RF Energy Harvesting

Radio-frequency (RF) energy harvesting is a promising candidate for alternative power source that can reduce the dependencies on batteries. However, its power density is very low which makes it crucial to have a high gain antenna to increase the power received by the system. This study presents the...
