| Abstract: |
| Recently, electromagnetic energy harvesting has garnered significant interest and attention. This study proposes a novel ultra-wideband antenna featuring an enhanced radiation pattern and a structure incorporating metamaterials. The goal is to improve forthcoming wireless power transfer systems. The antenna's design features a modified semi-circular monopole resonator with microstrip-line feeding, coupled with a trapezius ground along with an 8×8 array meta-surface. It incorporates compact metamaterial unit cells, designed as square rings with protruding octagonal ring parasitic structures. Both structures are implemented on an FR4. It is demonstrated that the proposed design operates effectively from 2.8 to over 12 GHz, encompassing the necessary spectra coverage (3.1-10.6 GHz) for UWB applications. The design exhibits satisfactory bandwidth, radiation characteristics, and gains, making it suitable for UWB and energy harvesting systems, meeting their requirements effectively. |
