Abstract :
This paper describes the design and the optimization of a quarter-wave patch antenna with a Thermo-Electric Generator (TEG). The antenna operates in the Industrial, Scientific and Medical (ISM) frequency band 2.4-2.5 GHz. The TEG, mounted on the top of the antenna, is used to perform thermal Energy Harvesting (EH) in order to supply wireless nodes. This antenna topology is chosen in order to provide a good thermal transfer between the TEG and the ground plane of the antenna. The antenna design consists of the optimization of its radiation properties in presence of the TEG electromagnetic model. Finally, a prototype of the antenna was fabricated and the TEG was mounted on its top. The measurements show a reflection coefficient lower -10 dB in the overall frequency band and a gain of 2.3 dB at 2.45 GHz.
