Problems solved by technology

Traditional 2G indoor distribution systems (GSM 800MHz systems, etc.) generally use single-polarized antennas, and future 3G systems have higher requirements for signal polarization multiplexing, and single-polarized antennas are no longer suitable for this requirement. In addition, 2G indoor distribution The system is often around 1GHz signal frequency such as 800MHz, 900MHz, etc. The wavelength of the signal is longer, and the indoor environment has little influence on electromagnetic waves. In contrast, the frequency band of the 3G system is generally higher, such as the frequency band of the TD-SCDMA system is 1880-2025MHz , the frequency band of its evolution system TD-LTE is as high as 2570-2620MHz, the penetration ability of electromagnetic waves is greatly weakened, and the probability of blind spots indoors is significantly increased

Embodiment Construction

[0019] like Figure 1 to Figure 3 As shown, the embodiment of the present invention provides an indoor dual-polarized omnidirectional antenna, which mainly includes a metal reflector 1, a vertically polarized antenna 2 whose axis is perpendicular to the metal reflector 1 and fixed on the metal reflector 1, and The horizontally polarized antenna 3 is fixed above the vertically polarized antenna 2. In this way, the indoor dual-polarized omnidirectional antenna can include two different polarizations, vertical and horizontal. Through the combination of such a special structure, on the one hand, it meets the needs of wide-band The requirements of signal coverage and high gain avoid indoor communication blind spots and improve the quality of mobile communication services. On the other hand, it avoids the problem of repeated antenna construction caused by multi-band coverage, which meets the requirements of energy saving and emission reduction. specifically:

Abstract

The embodiment of the invention relates to an indoor dual-polarized omnidirectional antenna. The antenna comprises a metal baffle plate, a vertical polarized antenna of which an axis is vertical to the metal baffle plate and which is fixed on the metal baffle plate, and a horizontal polarized antenna fixed above the vertical polarized antenna. By the indoor dual-polarized omnidirectional antenna disclosed by the embodiment of the invention, due to the special structure of the indoor antenna with wider frequency band coverage and a higher gain, a signal coverage requirement of a wide frequency band is met, an indoor communication blind area is avoided, the mobile communication service quality is improved, the problem of repeated antenna construction caused by multi-frequency band coverage is avoided, and the requirements of saving energy and reducing emission are met.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an indoor dual-polarized omnidirectional antenna. Background technique [0002] At present, the transmission and coverage of indoor signals is an important part of mobile communication, which is completed by the indoor distribution system. Traditional 2G indoor distribution systems (GSM 800MHz systems, etc.) generally use single-polarized antennas, and future 3G systems have higher requirements for signal polarization multiplexing, and single-polarized antennas are no longer suitable for this requirement. In addition, 2G indoor distribution The system is often around 1GHz signal frequency such as 800MHz, 900MHz, the wavelength of the signal is longer, and the indoor environment has little influence on electromagnetic waves. In contrast, the frequency band of the 3G system is generally higher, such as the frequency band of the TD-SCDMA system is 1880-2025MHz , the frequency band of its ev...
