Embodiment Construction

[0028] In this example, if figure 1 As shown, according to the requirements of modern wireless communication on bandwidth and anti-interference indicators, an ultra-wideband all-metal circularly polarized antenna unit is designed. The antenna unit has ultra-wideband, wide-axis ratio bandwidth, and circular polarization. With the advantages of miniaturization, simple feeding, and low loss, it can achieve full coverage in Band38, Band41, and Beidou frequency bands, making the antenna have faster transmission rates and stronger anti-multipath capabilities. Specifically, the antenna unit is composed of a fishbone-shaped crossed dipole radiation unit with a three-dimensional structure, a coaxial feed and a metal reflection cavity 10; the antenna is all made of metal materials, which can strengthen the physical strength of the entire antenna. The use time is more durable. On the one hand, the choice of all-metal structure ensures that the material is saved under the necessary suppo...

Abstract

The invention discloses an ultra wide band all-metal circular polarized antenna unit comprising a stereo structure fish-bone type crossed dipole radiation unit, a coaxial feed and a metal reflection chamber; the metal reflection chamber is arranged on the fish-bone type intersect dipole radiation unit; the coaxial feed penetrates the metal reflection chamber and a cylinder resonant cavity and is connected with the fish-bone type intersect dipole radiation unit; the fish-bone type intersect dipole radiation unit is the radiation area, the cylinder resonant cavity is the transmission area, and the coaxial feed is the feed area, thus receiving and transmitting energy. The ultra wide band all-metal circular polarized antenna unit can satisfy the requirements of modern wireless communication technology index on antenna bandwidth and anti-interference capability, thus allowing the antenna to have faster transmission rate and stronger anti-multipath capability.

Description

technical field [0001] The invention belongs to the technical field of modern wireless communication, and in particular relates to a novel ultra-wideband all-metal circularly polarized antenna unit. Background technique [0002] With the wide application of wireless communication, circularly polarized antennas can suppress rain and fog interference and anti-multipath reflection due to the reversal of rotation when circularly polarized waves are incident on symmetrical targets (such as planes or spherical surfaces). Among them, ultra-wideband circularly polarized antennas, as the key components used to transmit and receive electromagnetic waves in radio equipment, have received more and more attention. At present, UWB circularly polarized antennas have the following structural forms. Although they have their own characteristics in performance, they all have certain deficiencies. [0003] 1. Microstrip patch antenna. Because the antenna itself has low requirements for proces...
