Description Context:
Energy harvesting is the process by which energy is derived from external sources (e.g. solar power, EM power, thermal energy, wind energy, etc ...), captured, and stored for supplying small devices.
Energy-harvesting technologies are fundamental in enabling the realization of ‘‘zero-power’’ wireless sensors and their increasing utilization in low-power and power-efficient sensors and electronics could potentially find application in numerous critical areas ranging from health, agricultural, structural health monitoring to logistics, localization, and security.
As there are some frequency bands that are widely used (i.e. GSM, 3G, 4G, WiFi, digital TV, etc …) the challenging part is to design a small multiband antenna able to harvest as much power as possible.

The aim of this project is to create a miniaturized antenna for energy-harvesting applications. There are two main challenges for this assignment: first of all, in order to take more power from the environment, double or multi-band antennas are required and secondly those antennas must be small enough to be integrated on printed circuit boards.

The development of the project will start with the analysis of the state-of-the-art concerning the design and miniaturization of antennas. After this preliminary part the student will go through the actual design of a multiband miniaturized antenna for energy harvesting applications.

Required skills The candidate should be a student preferably from a master degree in electrical or electronic engineering. Knowledge of basic laboratory instrumentation, RF design and antennas is needed.
