Dual-band tri-polarized antenna based on closed mushroom-shaped unit structure

Abstract

The invention discloses a dual-band tri-polarized antenna based on a closed mushroom-shaped unit structure. The antenna is characterized by comprising a vertical polarization radiator and a horizontalpolarization radiator, wherein the vertical polarization radiator and the horizontal polarization radiator are fixedly connected to form a cake-shaped structure, the vertical polarization radiator and the horizontal polarization radiator are both of a multi-layer stacked structure, the multi-layer stacked structure comprises a plurality of layers of concentric circles, the concentric circles comprise a plurality of dielectric substrates, the vertical polarization radiator and the horizontal polarization radiator respectively comprise a plurality of closed mushroom-shaped unit structures, eachclosed mushroom-shaped unit structure comprises at least three metal layers and metal short-circuit pins, and the short-circuit pins are at least connected with two layers of the metal. According tothe structure, by controlling the dispersion characteristic of the closed mushroom-shaped unit structure, the multi-frequency directional diagram diversity radiation equipment which has the vertical polarization radiation characteristic and the dual-horizontal polarization radiation characteristic at the same time in two specified frequency bands can be designed on the basis of the structure.

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
