Design of the Ladder Multi-slot Fractal Split Growth Array Antenna

Abstract

Abstract According to the performance requirements of the ultra-wideband multi-band compatible antennas for microwave band multi-network integration systems, the present paper originally combines the structure of ladder multi-slot, “Embedded” slot fractal iteration and the split growth array, designs a ladder multi-slot fractal split growth array antenna. The result of test indicates that this antenna can completely cover all working frequency bands of the mobile communication system, the frequency bands of the radio frequency identification system, the frequency band of the ultra-wideband system and the frequency band of the mobile digital TV system. With the advantages of small size, high radiation intensity and stable radiation characteristics, it can be applied to large-scale applications in the multi-network system of microwave frequency band.
