- Thermoelectric Device Based on Microstrip Nanoantennas for Distributed Radar Networks Javier Mendez‐Lozoya Francisco J. González Emanuel Salinas Steven Keller Miguel José Yacaman Microwave and Optical Technology Letters ABSTRACTA device comprised of gold patch antennas with Bi2Te3 and Sb2Te3 thermoelectric lines has been fabricated using optical lithography and characterized using a vector network analyzer (VNA) to analyze the thermoelectric voltage as a function of electromagnetic power. Simulation results show that this device has a resonance at 10 GHz. The calculated bandwidth for this dual microstrip patch is 7 GHz which is an improvement over non‐thermoelectric rectangular microstrip patches which are known to be narrow‐band antennas. Experimental results where the source antenna power was varied from 0 to 10 mW (−20 dB) show that the resulting thermoelectric voltage measured at the thermoelectric antenna ranged from 0 to 17.5 µV. Hence, the thermoelectric device based in microstrip nanoantennas has a responsivity of 1.75 µV/mW. 10.1002/mop.70069 http://onlinelibrary.wiley.com/termsAndConditions#vor
