Abstract :
Two kinds of novel miniaturized dual-band antennas are proposed, which is worked as Radio Frequency Identification (RFID). Their arms carried by bending or simply fractal like tree form based on conventional dipole antenna So they can realize electric small size and dual band with its bent arms. This paper gives design of unequal length arm rounded U-shaped antenna and round notched antenna. Experiment and measurements on the implemented antennas show the antennas work well, in which can be seen that the dual band frequency center is 1.8 GHz and 2.4 GHz. The electric small size can get 0.30 λ and 0.42 λ.
