Abstract:
In this paper, the impact of slots on the patch antenna performance for energy harvesting applications is studied. The aim of this study is to exploit the role that slots play in patch antennas to control and adjust the resonant frequency of energy harvesting systems. This feasibility allows the designer to target the available source of electromagnetic energy. Three types of patch antennas were employed these are rectangular patch with inset feeding and one slot on the front patch, rectangular patch with double slots and UWB circular patch. CST MWS is used to simulate the proposed structures. The results showed that changing the dimensions of the slots and varying the distance between them have a direct and significant impact on the resonant frequency of the antenna.
