Problems solved by technology

[0005] Conventional base station sector antennas for wireless metropolitan area networks often use a parallel feeding method to meet the requirements of equal amplitude and phase between each array element. High electrical radiation in side lobe and back lobe
In addition, in order to ensure a certain antenna bandwidth, the microstrip array antenna often needs to adopt a multi-layer patch design, which increases the thickness and weight of the antenna, and the structure and preparation process are relatively complicated, and the repeatability of mass production is poor. The high preparation cost is not conducive to the miniaturization and light weight of the base station sector antenna for wireless metropolitan area network

Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, a base station sector antenna for a wireless metropolitan area network has a three-layer structure consisting of a dielectric plate 1, a foam medium 2, and a metal reflective back plate 3 from top to bottom, wherein the dielectric plate 1 can be made of polytetrafluoroethylene Ethylene, the foam medium 2 can be made of expandable polyethylene (also known as pearl cotton), and the metal reflective backboard 3 can be made of iron, aluminum, copper and other materials. The upper surface of the dielectric board 1 is provided with a feeder 4, and the lower surface of the dielectric board 1 is provided with a gap 5 surrounded by a metal ground 6. The number and arrangement of the gaps are two columns and eight rows. The feeder 4 adopts a feeding method combining series and parallel, and the current is in the form of a non-equiradial feeder that decreases from the middle to both ends.

[0017] The specific description is as follows:

Abstract

The invention discloses a base station sector antenna of wireless regional domain net, which comprises the following parts: dielectric board, foaming dielectric material and metal reflecting notum, wherein the gap is set on the lower surface of dielectric board, whose circumstance is metal; the feeder line contains several bars of first feeder line segment and one second feeder line segment; the arrangement pattern of gap is two-row multi-line; the first feeder line is set on each line gap; the second feeder line segment parallels the middle part of first feeder line segment. The invention possesses convenient preparing technology, which provides 300-400 MHz broad communication bandwidth.

Description

technical field [0001] The invention relates to a base station sector antenna, in particular to a base station sector antenna for a wireless metropolitan area network. Background technique [0002] With the continuous development of information technology, people's demand for communication networks is also increasing. When the core network bandwidth has reached the Tbit level, the bandwidth rate of the access network has become the bottleneck restricting high-speed data transmission. [0003] WiMax, the full name of which is World Interoperability for Microwave Access, is a wireless metropolitan area network (WMAN) access technology. It is synonymous with the 802.16 standard and is a new air interface standard proposed for microwave and millimeter wave frequency bands. It is used to connect 802.11 wireless access hotspots to the Internet, and can also connect environments such as companies and homes to wired backbone lines. It can be used as a wireless extension technology...
