Problems solved by technology

The dual-frequency dual-polarization omnidirectional antennas involved in the existing literature and patents are almost all realized by dual-port feeding, which can neither realize the miniaturization of the antenna, save space, but also complicate the structural design. In addition to increased assembly and installation costs

Abstract

The invention discloses a single-port dual-frequency dual-polarization omnidirectional antenna applied to WIFI, comprising a reflector, a first dielectric plate placed horizontally and a second dielectric plate placed vertically. The upper and lower surfaces of the first dielectric plate are symmetrical A first dipole antenna and a second dipole antenna are attached to form a dipole antenna array consisting of four dipole antennas, which are used to realize the omnidirectional radiation and horizontal polarization characteristics of the 5G signal, and the second The first surface of the dielectric board is attached with a radiator and a feed wire, and the second surface of the second dielectric board is attached with a ground wire. The middle of the radiator is connected to the feed wire to form a feed point. The reflector is connected to form a loop, which is used to realize the omnidirectional radiation and vertical polarization characteristics of the 2.4G signal. The omnidirectional antenna provided by the present invention has single port, dual frequency, horizontal and vertical dual polarization, wide frequency, small size, full Good tropism and high average gain.

Description

technical field [0001] The invention belongs to the field of antenna design, and in particular relates to a single-port dual-frequency dual-polarization omnidirectional antenna applied to WIFI. Background technique [0002] In the past ten years, with the rapid development of the information technology industry, the number of electronic devices that need to be connected to the Internet has increased dramatically, and the corresponding requirements for WIFI devices have become higher and higher. Omnidirectional coverage of signals and high data transmission rates are now important performance indicators for WIFI devices. At present, most wireless communication devices use omnidirectional antennas or smart antenna beam scanning to achieve omnidirectional coverage, and use MIMO antenna technology to achieve high data throughput. However, in some relatively open places, due to weak multipath reflections, space diversity cannot be achieved. For higher throughput rates, polarizat...
