Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The present invention is an ultra-broadband omnidirectional antenna binary array with a pure metal structure, the structure of which is as follows figure 1 As shown, it includes a pair of metal plates 2 arranged in parallel up and down, and air is filled between the pair of metal plates 2. The upper surface of the upper metal plate 2 is vertically connected with a pair of radiation array arms 1, and the bottom of the lower metal plate 2 The surface is also vertically connected with a pair of radiation element arms 1 , and a coaxial SMA feed head 3 is also arranged at the center of the lower surface of the lower metal plate 2 .

[0023] The distance between a pair of metal plates 2 is 0.01-0.08 times the wavelength.

[0024] The length of the metal plate 2 is 50 mm, which is between 1 / 5-1 / 2 wavelength, and the width is 24 mm, which is ...

Abstract

The invention discloses an ultra-wideband omnidirectional antenna binary array with a pure metal structure. The array comprises a pair of metal flat plates arranged in parallel up and down, wherein air is filled between the pair of metal flat plates, the upper surface of the metal flat plate at the upper part is vertically connected with a pair of radiation oscillator arms, the lower surface of the metal flat plate at the lower part is also vertically connected with a pair of radiation oscillator arms, and a coaxial SMA feed head is also arranged at the central position of the lower surface ofthe metal flat plate at the lower part. According to the invention, the problems that the impedance bandwidth of the traditional omnidirectional antenna is limited and good horizontal omnidirectionalradiation is difficult to realize at each frequency point in the band in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication and microwave omnidirectional coverage, and in particular relates to a dual array of ultra-wideband omnidirectional antennas with a pure metal structure. Background technique [0002] Due to the crucial role of antennas in the entire communication link, with the rapid development of wireless communication systems, various antennas have been proposed to meet higher requirements. As far as the current antenna usage is concerned, the omnidirectional antenna can achieve 360° coverage in the horizontal plane. Whether it is civilian or military, there are many examples of omnidirectional antennas in communication environments, such as radio frequency identification, radio and television, and aircraft. At the same time, due to the complex and changeable communication environment and the improvement of communication requirements, a wider frequency band is also required for omnidirectional an...
