Small-sized quick-assembling dual-polarized high isolation antenna

Abstract

The invention discloses a small-sized quick-assembling dual-polarized high isolation antenna, which comprises a reflecting surface, a feed source, a plastic supporting outer shell and a fixed base, and is characterized in that the reflecting surface comprises a primary paraboloidal reflecting surface and a secondary paraboloidal reflecting surface, the primary paraboloidal reflecting surface is composed of a plurality of paraboloid units, and the feed source comprises two groups of dipole antennas which are perpendicular to each other. Compared with the traditional reflecting surface integrated forming design, the die stamping size is reduced, the production cost is decreased, the paraboloid units are identical in shape and size, and the paraboloid units can be placed and packaged in a stacking manner, thereby reducing the packaging size and facilitating transportation; and the feed source comprises the two groups of dipole antennas which are perpendicular to each other, the signal transmitting / receiving capability is enhanced, the isolation between the antennas can be improved by adjusting the distance between the two groups of dipole antennas, and the anti-interference capability of the feed source is enhanced.

Description

technical field [0001] The invention relates to an antenna, in particular to a small, fast-installed dual-polarized high-isolation antenna. Background technique [0002] An antenna is a transformer that converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa, so the antenna is a radio device used in Components that emit or receive electromagnetic waves are widely used in engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy. [0003] As a high-gain antenna for point-to-point communication, the parabolic antenna is often used for the relay and transmission of long-distance signals, such as telephone and TV signal communication between cities, wireless WAN / LAN link data communication, satellite communication, etc. In addition, parabolic antennas are also used in radio ...

AI Technical Summary

Problems solved by technology

[0004] However, most of the reflective surfaces of parabolic antennas currently adopt integrated molding design. The stamping size of the mold is too large, the price is expensive, and the requirements for processing equipment are relatively high, which also causes problems such as difficult product packaging and transportation. , the risk of decreasing structural strength and accuracy

In addition, the commonly used parabolic antennas mostly adopt single-polarization design, and the anti-interference ability of the antenna is limited
