Projecte realitzat en col.laboració amb el Centre Tecnològic de Telecomunicacions

The work focuses on designing, measuring and testing an antenna and recti er circuit (RECTENNA) optimized for incoming signals of low power density. The rectenna is used to harvest electric energy from the RF signals that have been radiated by communication and broadcasting systems at ISM band centred in 2.45 GHz., This work contains methods to simulate rectennas with Harmonic Balance and electromagnetic full-wave Momemtum by Agilent Advanced Design Software, used of LPKF Milling machine for antenna fabrication , Vector Network Analyzer, spectral analyzer, digital generator, multimeter, and anechoic chamber for antenna and recti er measurements. The work is motivated by two types of applications: powering of low-power sensor and RF energy recycling being aware of the energy consumption and e ect to the natural environment. The goal of this work is to determine the usefulness of low-power recti cation
