Journal of Photonics for Energy, 7(2).1947-7988https://hdl.handle.net/10877/9650The authors investigate the efficiency of a series of broadband rectennas designed to harvest the free-propagating electromagnetic energy at terahertz frequencies. We analyze by simulations the case of self-complementary square- and Archimedean-spiral antennas coupled to L-shaped self-switching diodes (L-SSDs). First, the geometry (i.e., the width and length of the channel) of the L-SSD was optimized to obtain a remarkable diode-like I–V response. Subsequently, the optimized L-SSD geometry was coupled to both types of spiral antennas and their characteristic impedance was studied. Finally, the energy conversion efficiency was evaluated for both rectenna architectures.Text12 pages1 file (.pdf)enterahertzself-switching diodesspirals antennasenergy harvestingimpedance matchingIngram School of EngineeringArticle© 2017 Society of Photo-Optical Instrumentation Engineers.https://doi.org/10.1117/1.JPE.7.025001
