Abstract
AbstractIn this paper, the radiative near‐field method has been employed to transfer power through a triangular patch microstrip array that had not been used for this application previously. Additionally, the FR4 substrate is utilized to further reduce the system cost. The system comprises two identical array antennas functioning as both transmitter and receiver. Each array consists of four triangular patches with a side length of 38.5 mm and operates at a frequency of 2.4 GHz. The distance between the two arrays is 50 mm, placing the system in the radiative near‐field category of wireless power transfer. This two‐array system enables the evaluation of power transfer efficiency. The system's performance is improved compared to that of a single triangular patch, and it is also studied in terms of changes in distance. As expected, reducing the distance enhances the system's performance. Subsequently, the structure is fabricated, and the measurements validate the simulation results. The simulation and measurement results exhibit good agreement.
