Abstract: A hexagonal fractal broadband microstrip antenna for L-band, S-band and C-band is proposed. The second-order hexagonal Sierpinski fractal structure is used as the radiation patch, and the microstrip feeding technology is used for feeding. Through simulation analysis and model optimization, the final size of the antenna is 36 mm×28 mm×1.6 mm, the relative bandwidth of -10 dB impedance is 150.3%(1.10~7.76 GHz), and the maximum peak gain is 7.80 dB at 1.10 GHz. The antenna has the advantages of simple structure, small size, large bandwidth and good gain, which can be used in various broadband communication systems.
