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...

Abstract

The invention relates to a microstrip antenna based on a two-order Sierpinski carpet fractal structure. The microstrip antenna comprises the two-order Sierpinski carpet fractal structure (11), two rectangular angles with the same size (12) and (13), and a 50 ohm coaxial feeder line structure (20), wherein the two-order Sierpinski carpet fractal structure (11) consists of a large rectangle (14) in the middle part and eight small rectangles with the same size at the surrounding, and the two rectangular angles with the same size (12) and (13) are symmetrically distributed along the auxiliary diagonal line of a metal microstrip patch area, and are respectively positioned at the left upper corner and the right lower corner of a metal microstrip patch. The microstrip antenna has the characteristics that the structure is compact, the size is small, the frequency band is wide, the processing is easy, and the like.

Description

technical field [0001] The invention relates to an antenna, in particular to a microstrip antenna based on a Sierpinski square carpet fractal structure. Background technique [0002] In recent years, with the development of wireless communication technology and the popularization of wireless communication application products, especially the popularity of handheld wireless communication devices, wireless communication devices have been made smaller and smaller so that users can carry them with them. This makes people have higher requirements for the antenna used for wireless communication, that is, the antenna should be miniaturized. [0003] Since the French mathematician Benoit-Mandelbrot first proposed the concept of fractal in 1973, fractal geometry has attracted the attention and research of many scholars. In the 1980s, there were more studies on the interaction between waves and fractal structures, which promoted the development of fractal electrodynamics, and fractal...
