In view of the requirements of multiple frequency bands working systems, such as mobile communication system and the Radio Frequency Identification（RFID） system, a new divisive growing type fractal structure is proposed. The PI type quadrilateral snowflake structure is used to going on divisive growing type fractal iterative calculation, with which implements a highly integrated equivalent composite radiation edge, and designed a divisive growing type fractal microstrip antenna. This antenna can cover the 900 MHz frequency band and 1.9 GHz frequency band of mobile communication system, 2.45 GHz frequency band of the RFID system at the same time. The return los
