Problems solved by technology
[0003] At present, in the terminal data connection of the wireless communication system, the project has better solved the problems that the antenna is limited by the volume, transmission capacity and rate, and the frequency band used, which affects the user experience and the beauty of the environment, multi-device connection error codes, and dropped calls.
[0004] The antennas used in existing indoor coverage mobile communication systems are all external single-frequency single-polarization, external single-frequency dual-polarization, external single-frequency multi-polarization, external dual-frequency single-polarization, and built-in dual-frequency Single-polarization and other installations are bulky, and multiple installations must be repeated within a usable space to meet multi-frequency and multi-polarization network coverage, resulting in waste and high production costs in use and installation

Embodiment Construction
[0019] The technical solution will be described in detail below in conjunction with specific embodiments.
[0020] like Figure 1-Figure 3 As shown, the present invention is a built-in multi-frequency dual-polarized split indoor omnidirectional antenna, which includes two built-in multi-frequency dual-polarized shrapnel antennas 2 fixed on the active micro base station circuit board 1, two built-in multi- The high-frequency dual-polarized shrapnel antenna is installed in the same plane with a 90° dislocation, and is fixed by a dual-antenna card slot or a screw on the back to realize two-polarized omnidirectional radiation and improve port isolation. Two built-in multi-frequency dipoles installed in a dislocation The polarized shrapnel antenna is used for welding feed, and the two built-in multi-frequency dual-polarized shrapnel antennas are split structures with the same volume and frequency band. Using the PIFA-like design concept, it is an open circuit or short circuit stru...

The invention discloses a built-in multi-frequency dual polarization split indoor omni-directional antenna. The antenna is characterized in that the antenna comprises two built-in multi-frequency dual-polarization elastic sheet antennas fixed on an active micro base station circuit board, and two built-in multi-frequency dual polarization elastic sheet antennas are arranged in dislocation at 90 degrees. According to the invention, the isolation between vertical and horizontal ports of the antenna in the working frequency band is 20 to 25 (-DB); the standing wave (VSWR) is less than or equal to1.8; the gain is greater than 2.5 dBi; the polarization is vertical / horizontal; the efficiency is greater than 70%; the -3dB lobe width (VB) of the vertical plane is greater than 35 degrees; and thebuilt-in multi-frequency dual polarization elastic sheet omni-directional antenna has the advantages of novel design, less structure components, simple assembly, low cost, small size and superior performance.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically relates to a multi-frequency dual-polarized omnidirectional antenna device. Background technique [0002] With the vigorous development of mobile communication technology and the popularization and application of terminal equipment, wireless communication data connection is closely related to people's work, study and life. The wireless transceiver antenna at the end of the mobile communication indoor coverage system, after more than 10 years of development, has been spread in various indoor public places such as large supermarkets, hospitals, underground parking lots, conference centers, hotels, etc. Be a bridge for information connection. The antennas of these indoor separation systems are relatively large in size, which affects the appearance, and the installation is complicated and has many auxiliary procedures and a large workload. According to t...
