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

Description

technical field [0001] The invention belongs to the field of antenna design, in particular 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 sharply, and the corresponding requirements for WIFI devices have also become higher and higher. Omni-directional coverage of signals and high data transmission rate are now important performance indicators of WIFI equipment. Current wireless communication devices mostly use omnidirectional antennas or smart antenna beam scanning to achieve omnidirectional coverage, and high data throughput is achieved through MIMO antenna technology. However, in some relatively open places, space diversity cannot be realized due to weakened multipath reflections. For higher throughput, polarization diversi...
