According to the requirements of the mobile communication system, radio frequency identification system, ultra wideband system and the mobile digital TV system to the antenna's performance, the present paper originally combined butterfly shaped bionic antenna and Hilbert fractal array, designed a high compatibility fractal array bionic antenna, fabricated the antenna sample and tested the radiation characteristics of the antenna. The result of test indicate that this antenna completely covered all working frequency bands of the second generation to the fifth generation mobile communication, the frequency bands of the radio frequency identification system, the frequency band of ultra wideband system, and the frequency band of the mobile digital TV system. The smart terminal using this antenna will have many functions, such as mobile communication, radio frequency card read and write, ultra wideband transmission, mobile digital TV and so on, and this antenna has great potential for application.
