Abstract

A novel fractal plane ultra-wideband antenna belongs to the wireless communication technical field. The novel fractal plane ultra-wideband antenna is composed of a medium plate (3), a radiation unit (2) and a feed unit (4) printed on one face of the medium plate (3) and directly communicated with each other, and a grounding unit (6) printed on the other face of the medium plate. The radiation unit (2) is a metal patch formed by performing iterative fractal operations twice or more times and being a communicating body. A slit (1) is etched on the radiation unit. The grounding unit (6) is a trapezoidal metal patch. A rectangular groove (5) is etched on the central position of the grounding unit upper bottom edge. The novel fractal plane ultra-wideband antenna has the advantages of ultra wide band, good directivity, low standing-wave ratio, small volume, lightness, low profile, low cost, easy processing, easy circuit integration, relatively low manufacturing cost, high precision and repeatability. The antenna which achieves great impedance match is suitably used for miniaturized equipment. Batch production is further facilitated.

Description

technical field [0001] The invention relates to a novel fractal ultra-wideband antenna and belongs to the technical field of wireless communication. Background technique [0002] With the rapid development of the wireless communication field, the miniaturization of terminal communication equipment has become a trend. A typical feature of planar antennas is small size, low profile, light weight, and small size, so miniaturized planar antennas can be easily applied to mobile terminals. [0003] As the transmitting and receiving part of the wireless communication system, the antenna not only requires the antenna to be miniaturized, but also requires the characteristics of multi-band and wide-band. Combining the self-similarity and space-filling properties of the fractal structure, when applied to the antenna design, the antenna can achieve multi-frequency and miniaturization. At the same time, the fractal structure can be adjusted to make multiple resonance points close to eac...
