Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Referring to Fig. 1 (a) and (b), it is a preferred embodiment of a small ultra-wideband omnidirectional fractal patch antenna provided by the embodiment of the present invention. According to the description shown in FIG. 1, the patch antenna mainly includes: a metal radiation patch 1, an intermediate dielectric plate 2, a metal ground plate 3 and a microstrip feeder 4. The middle layer dielectric plate 2 is made of RO4003 material with a thickness of 0.813 mm and a dielectric constant of 3.38.

[0021] The metal radiation patch 1 is composed of a circular patch and a microstrip, wherein a circular slot is made in the center of the circular patch, and then the equilateral triangular slots are nested in an axisymmetric structure to form a fractal structure so that the antenna has multi-frequency characteristics.

Abstract

The invention discloses a micro ultra wide band omnidirectional fractal paster antenna. The antenna comprises a metal radiation paster, an interface layer medium plate and a metal ground plate, wherein the interface layer medium plate is arranged between the metal radiation paster and the metal ground plate, the metal radiation paster comprises a circular paster and a microstrip feed line, the center of the circular paster is taken as a circular groove, the polygon groove is embedded in an axisymmetric structure mode to form a fractal structure to make the antenna have multi-frequency characteristics, a lower small portion of the top portion of the circular paster is transversely sectioned and removed to reduce antenna dimensions, and the metal ground plate is formed by grooving a rectangular metal paster to facilitate broadband impedance matching. The antenna is advantaged in that properties of simple and novel structure, small dimensions, stable directional diagram, good omnidirectivity, wide bandwidth and easy processing are realized, and the antenna can be applicable to mobile communication and radio frequency identification fields.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a novel ultra-wideband antenna, specifically a small fractal antenna which can be used for wireless communication and has good omnidirectional characteristics. Background technique [0002] With the development of society, wireless communication is playing an increasingly important role in life, and antennas are an important part of the system, and people have put forward higher and higher requirements for broadband and miniaturization. Broadband antennas can not only meet the needs of high-speed transmission of a large amount of information between people, but also enable one antenna to work in multiple communication system frequency bands, thereby reducing the number of antennas on the carrier and realizing the miniaturization of communication equipment. With the further development of microwave technology, microstrip antennas with low cost, simple structure and easy integra...
