Abstract
In this thesis, a triangular microstrip patch antenna is used to transfer wireless power at 2.4 GHz. First, the simple patch antenna is studied and its performance is investigated. Then, the new design is introduced to boost the efficiency and transmission coefficient of the simple patch antenna. Since the simple patch aimed to operate at 2.4GHz, its dimension is optimized to be 56mm with a reflection coefficient of -28.2 dB at the resonance frequency. An identical patch acting as a receiver is then placed in a 50mm distance to the main patch acting as a transmitter to enable us to measure the power transferred to the receiver antenna. The transmission coefficient between the two simple patches is -3.5 dB at the resonance frequency of 2.4 GHz. Furthermore, the proposed array is designed and simulated yielding a reflection coefficient of -28 dB at 2.4 GHz. The same procedure for the simple patch is followed to obtain the transmission coefficient of -0.55 dB at 2.4 GHz. The simulation results show 89% efficiency for the proposed structure compared to the 44% efficiency of the single patch. Similarly, the structure is studied for 5.8 GHz and the corresponding results are provided. A titled version of the structure is also investigated and a similar efficiency as the original proposed structure is reported.
