Abstract

This paper presents a solar cell coplanar patch antenna designed to operate in the 2.4 GHz band. The simulation results were validated by the solar cell antenna’s prototype fabrication and characterization. The proposed antenna has a gain of $4.13 \mathrm{dBi}, 15.14 \%$ bandwidth, and efficiency of $87.1 \%$ at 2.45 GHz. Also, the I-V curves of the solar cell were extracted for indoor irradiation levels. The $I_{S C}$ and the $V_{O C}$ were $2.35 \mathrm{~mA}$ and 135 mV, respectively, supplying $100 \mu \mathrm{W}$ in the maximum power point. The satisfactory results endorse the operability of the prototype for simultaneous operation as solar energy harvesting and radiator element.

以太阳能电池为辐射体的2.4 GHz共面贴片天线用于通信和能量收集

本文提出了一种工作在2.4 GHz频段的太阳能电池共面贴片天线。仿真结果通过太阳能电池天线的原型制作和表征得到验证。该天线在2.45 GHz时的增益为4.13，带宽为15.14%，效率为87.1%。同时，提取了太阳能电池在室内辐照水平下的I-V曲线。$I_{S C}$和$V_{O C}$分别为$2.35 \mathrm{~mA}$和135 mV，在最大功率点提供$100 \mu \mathrm{W}$。实验结果表明，该样机可作为太阳能收集和辐射元件同时运行。
