Embodiment Construction

[0020] The structure and effects of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] refer to figure 1 with figure 2 , the antenna of the present invention is composed of three-sided six-array ±45° dual-polarized plate-shaped directional antenna and three-sided six-array 0° / 90° dual-polarized plate-shaped directional antenna. Among them, each ±45° dual-polarized plate-shaped directional antenna is composed of a trapezoidal reflector A and eight ±45° dual-polarized oscillators X. The bottom edge L of the trapezoidal reflector 11 with its side L 12 There is an included angle θ between 1 ;Each side of the 0° / 90° dual-polarized plate-shaped directional antenna is composed of a trapezoidal reflector B and eight 0° / 90° dual-polarized oscillators S, the bottom edge L of the trapezoidal reflector 21 with its side L 22 There is an included angle θ between 2. Place ±45° dual-polarized plate-shaped directional...

Abstract

The invention relates to a polarization array omnidirectional antenna of the PHS's base stations and mainly solves the problems of poor signal and small percentage of coverage of the tri-sector polarization diversity omnidirectional antenna in the PHS's base stations. We arrange the three minus or plus 45 degrees dual-polarization platy directional antennas with three 0 degree / 90 degrees dual-polarization platy directional antennas interlacedly on the baseline of a hexagon to form the hexad-sector twelve-array minus or plus 45 degrees and 0 degree / 90 degrees qua-polarization diversity antenna structure and carry out the threeway power synthesis to the directional antenna with same degree. The terminals of the hexad-sector antenna export four cable wires of +45 degree, -45 degrees, 0 degree and 90 degrees and connect with the base station to realize receiving and sending out the signal with different polarization methods. The antenna has an omnidirectional radiation directional diagram in the horizontal plane. Compared with the common level omnidirectional antenna, the gain of every polarization terminal is more than 12.5dB, the isolation between any two terminals is less than -25dB and it improves the coverage of the omnidirectional base stations greatly and increases the covering distance of the base stations.

Description

technical field [0001] The invention belongs to the field of communication antennas, in particular to a four-polarized six-sector array omnidirectional antenna, which can be used as a polarization diversity omnidirectional antenna of a PHS base station and an omnidirectional antenna in mobile communication. Background technique [0002] With the development of the communication industry, people put forward higher requirements for the quality of mobile communication, especially the PHS PHS communication system, and one of the important means to improve the communication quality, that is, increase the signal strength is to increase the base station density. However, the increase in the number of base stations will not only occupy space and affect the beautification of the environment, but also increase investment. Therefore, how to use the existing base station to improve the performance of the antenna itself has become an important means to solve the problem of mobile communi...
