Problems solved by technology

[0002] Antenna is a device used to radiate and receive electromagnetic waves in radio equipment. It is one of the indispensable components of radio communication, radar, navigation, remote sensing, telemetry, radio astronomy and electronic countermeasures. There are two polarization methods for satellite receiving antennas. Type: one is linear polarization, the other is circular polarization; among them, under the line polarization mode, it is divided into horizontal polarization and vertical polarization; the existing horizontal omnidirectional circular polarization antenna adopts clover, four-leaf To achieve circular polarization in the form of grass, the antenna gain is difficult to synthesize high gain; or the circularly polarized array antenna is placed in a complex ring with a centimeter network, the diameter is relatively large, and the cost is relatively high

Abstract

The invention discloses a horizontal omnidirectional circularly polarized antenna, which comprises a base plate, an output connector disposed at the lower end of the base plate, a vertically polarized antenna disposed at the upper end of the base plate, and a vertically polarized antenna disposed at the upper end of the base plate and sheathed outside the vertically polarized antenna Polarized radome, the output connector passes through the bottom plate upwards and connects with the vertically polarized antenna, the shape of the polarized radome is a hollow tube, the vertically polarized antenna is located at the axis of the polarized radome, the The outer surface is obliquely covered with a plurality of metal polarization grids, which are arranged in sequence and spirally rotated in the shape of a grid; through the spiral metal polarization grid, the linearly polarized electromagnetic wave can be converted into a circular pole. The electromagnetic waves of the polarization form a light-weight, high-reliability high-gain horizontal omnidirectional circularly polarized antenna, which realizes circularly polarized characteristics with a very simple structure.
