Embodiment Construction
[0019] In recent years, fractal structures have been widely used in the design of microstrip antennas. Microstrip antennas with fractal structures use the self-similarity of fractal structures to increase the effective electrical length of the antenna, thereby reducing the size of the antenna. The fractal microstrip antenna overcomes the defects of sacrificing bandwidth and increasing complexity in traditional antenna miniaturization design. The present invention uses the second-order Sierpinski square carpet fractal structure to design a microstrip antenna with low cost, small size, wide frequency band and wide application range.
[0020] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] An example of the present invention is figure 1 As shown, it consists of a second-order Sierpinski square carpet fractal structure (11), two equal-sized rectangular cut corners (12), (13) and a 50-ohm coaxi...
