摘要：
The special space filling capability of Koch fractal is used in the Radar Cross Section (RCS) reduction of microstrip patch antenna. Compared with normal rectangular microstrip patch antenna, the resonance sides are designed in the shape of Koch fractal, while two Koch fractal shape slots are cut in the antenna. Based on the design, antenna prototypes were fabricated and tested, which shows that the gain loss was no larger than 1dB. The RCS of the fractal antenna is effectively reduced both in band and out of band compared with the rectangular patch antenna, while the radiation performance are almost maintained.
