ABSTRACT
As the number of portable communication devices is increasing tremendously, the design of low profile communications system is in high demand nowadays. The size of antenna can be designed with many kinds of miniaturization techniques. This thesis presents the design of a fractal patch microstrip antenna and a simple rectifying circuit. The antenna is a miniaturized first iteration Koch fractal island patch at 2.45 GHz ISM band (WiFi, RFID, Bluetooth, etc). It is intended for a rectenna which is used to harvest electric energy from bountiful the unused microwave RF signals into DC
