Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] A fractal ultra-wideband antenna of the present invention is composed of a dielectric board 3, a radiation unit 2 and a feeding unit 4 printed on one side of the dielectric board and connected directly, and a grounding unit 6 printed on the other side of the dielectric board. in:

[0026] a. The radiation unit 2 is a connected metal patch formed by two or more iterative fractals, and the slit 1 is etched on it;

[0027] b. The grounding unit 6 is a trapezoidal metal patch, and a rectangular groove 5 is etched in the center of its upper bottom edge.

[0028] The fractal method of the radiation unit 2 is:

[0029] a. Divide the circle with a radius R into six sectors with an angle of 60°, first cut off a small sector with a radius of R / 2 and an angle of 60° for each sector, and then graph the remaining six identical structures Expans...

Abstract

The invention provides a fractal ultra-wideband antenna, and belongs to the technical field of wireless communication. The fractal ultra-wideband antenna comprises a dielectric slab (3), a radiating unit (2), a feed unit (4) and a grounding unit (6), the radiating unit (2) and the feed unit (4) are printed on one face of the dielectric slab (3) and are directly communicated, and the grounding unit (6) is printed on the other face of the dielectric slab. The radiating unit (2) is formed after iteration and fractal carried out twice or more than twice and is a communicated metal patch, and seams (1) are etched on in the radiating unit; the grounding unit (6) is a trapezoid metal patch, and a rectangular groove (5) is etched in the center of the edge of the upper bottom. The antenna has the advantages that an ultra wideband is available, multi-frequency work is achieved, directionality is good, the standing-wave ratio is small and good impedance matching is achieved; the structure is simple, the size is compact, the weight is low, loss is low and requirements of plane design are met; the manufacturing cost is low, precision is high, repeatability is good and the antenna is suitable for being used for small devices and can be conveniently produced in a large scale.

Description

Technical field: [0001] The invention relates to a fractal ultra-wideband antenna and belongs to the technical field of wireless communication. Background technique: [0002] Ultra-wideband (UWB) technology is a new type of short-distance high-speed wireless communication technology that has attracted much attention at present. In 2002, the Federal Communications Commission (FCC) released an ultra-wideband wireless communication frequency band with a bandwidth standard of 7.5GHz, covering a frequency range of 3.1GHz-10.6GHz. In the industrial and academic aspects, ultra-wideband radio technology has invested a lot of research Work. Compared with other traditional wireless communication technologies, the technical characteristics of UWB mainly include high transmission rate, short communication distance, low average transmission power, good concealment, not easy to be intercepted, high confidentiality, high multipath resolution, suitable for Portable applications, etc. Tra...
