The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system. This possesses considerable challenges when designing efficient antennas for applications such as RF energy scavenging.
