这项工作证明了宽带接地互补开口环谐振器（WG-CSRR）阵列的可行性，与当前电磁能量收集系统中使用的技术相比，具有显着的功率转换效率和带宽增强。通过数值全波分析，我们证明了WG-CSRR贴片的拓扑结构和贴片上的电流分布在不同的频率之间的相关性。通过数值分析比较了WG-CSRRs阵列、G-CSRRs阵列和微带贴片天线阵列的功率收集效率和频率带宽。一个显着的改善，带宽相比，在早期的工作中报告的G-CSRR阵列实现。(C)2015 AIP Publishing LLC.
This work demonstrates the viability of wideband Ground-backed Complementary Split-Ring Resonator (WG-CSRR) arrays with significant power conversion efficiency and bandwidth enhancement in comparison to the technology used in current electromagnetic energy harvesting systems. Through numerical full-wave analysis, we demonstrated the correlation between the topology of the WG-CSRR patch and the electric current distribution over the patch at different frequencies. A comparative study of power harvesting efficiency and frequency bandwidth through numerical analysis was presented where an array of WG-CSRRs is compared to an array of G-CSRRs and an array of microstrip patch antennas. A significant improvement in bandwidth is achieved in comparison to the G-CSRR array reported in earlier work. (C) 2015 AIP Publishing LLC.
