The research works of this thesis are focused on the ambient electromagnetic energy harvesting to improve the life time of wireless autonomous devices. The waves produced by cellular telephones, Wireless Internet and also radio and television transmissions may be captured and rectified to produce a continuous voltage able to supply mobile phones, environment data sensors, computers, etc. Broadband or multiband antennas, combined to a high frequency rectifying circuits with Schottky diodes must be optimized for the reception and rectifying of a very low level electromagnetic power (about a few micro watts per cm2). In this thesis, an important optimization work is done in frequency domain and especially in power domain. The high frequency c...
