ABSTRACT:
A communication device (310) is provided that includes a nano-sized RF antenna (100) having low power consumption and wide-range frequency spectrum based on bottom-up nanotechnology. The antenna (100) includes an insulator layer (110) positioned between a free magnetic layer (112) and a fixed magnetic layer (108). A DC voltage source (124) is coupled to the free magnetic layer (112) and the fixed magnetic layer (108) for providing a current (118) therethrough. A detector (126) is coupled between the antenna (100) and the DC voltage source (124) for detecting a change in the current (118) in response to a radiated signal being received by the antenna (100) which causes a change in the spin on electrons in the free magnetic layer (112).
