Problems solved by technology

This type of antenna is more suitable for connecting single-band systems with different modes or different polarization requirements, but its diversity characteristics cannot be fully utilized
[0007] 3. Use each port to stimulate a working mode in two frequency bands at the same time, so that the diversity characteristics of polarization and pattern can be realized at the same time. However, the existing applications of this type of antenna are limited by the small number of polarizations and the profile high and low frequency ratio

Embodiment Construction

[0055] The present invention will be further described below with reference to the accompanying drawings.

[0056] As shown in FIG. 1, a dual-band triaturing antenna based on a closed mushroom-shaped unit structure includes a vertical polarizing radiator 1 and a horizontally polarized radiator 2, and the horizontally polarized radiator 2 is located vertically. The polarized radiator 1 is directly above, and the two are fixed with a nylon screw 3. The vertical polarized radiator 1 and the horizontal polarized radiator 2 include several such as Figure 7 The closed mushroom-like unit structure shown; the closed mushroom-like unit structure includes at least three layers of metal layers and metal short-pin needles; the short-pin needle is connected to two layers of the metal.

[0057] The coaxial waveguide port 2 of the horizontal polarized radiator 2 and the coaxial waveguide port 3 pass through the vertical polarized radiator 1, and the top-level circular patch 1a of the vertical po...

Abstract

The invention discloses a dual-band triple-polarized antenna based on a closed mushroom-shaped unit structure, which is characterized in that it includes a vertically polarized radiator and a horizontally polarized radiator; the two are fixedly connected in a pie-shaped structure; the vertical Both the polarized radiator and the horizontally polarized radiator are multi-layered structures, and the multi-layered superposed structure includes several layers of concentric circles; the concentric circles include several dielectric substrates; the vertically polarized radiators and The horizontally polarized radiators respectively include several closed mushroom-shaped cell structures; the closed mushroom-shaped cell structures include at least three metal layers and metal short-circuit pins; the short-circuit pins connect at least two of the metal layers. By controlling the dispersion characteristics of the closed mushroom-shaped cell structure, a multi-frequency pattern diversity radiation device can be designed with both vertical polarization radiation characteristics and dual horizontal polarization radiation characteristics in two specified frequency bands.

Description

Technical field [0001] The present invention belongs to the field of electronic devices of the wireless communication system, and more particularly to a dual-band triode antenna based on a closed mushroom-shaped unit structure. Background technique [0002] The continuous development of wireless communication technology and the rapid evolution of high integration of electronic devices, promoting information acquisition means and diversity of information interaction, and works in the wireless LANs. [0003] In modern communication systems, increasing the communication capacity of the system has become the key to the development of wireless technology. In order to provide multi-functional services, as well as normal work in complex electromagnetic environments, the communication system is rapidly increased for dual-band requirements, which requires antenna to operate at the multi-band segment to meet different frequency bands. On the other hand, a system with polarization and direc...
