| Abstract | ||||
| A compact Mickey-shape 2 1 microstrip patch antenna array is presented in this work for use in radio frequency (RF) energy harvesting applications in the industry, science, and medicine (ISM) band of 2.45 GHz. High-frequency structural simulator (HFSS) software was used to construct and model the antenna, and a vector network analyzer was used to measure the antenna parameters. The proposed structure has an overall dimension of 12×8 cm2 and spans a bandwidth of 2.42 GHz to 2.465 GHz. A 1.57 mm thick Rogers RT/Duroid substrate with a dielectric constant of 2.2 is used for modeling and manufacture. The modeling and experimental results show a very good performance in the operational band. Additionally, the results demonstrate enhanced antenna characteristics in terms of size, bandwidth, return loss, and efficiency. At 2.45 GHz, the suggested antenna has a high gain of 9.215 dBi. The findings demonstrate a strong agreement between measurements and models. | ||||
