Problems solved by technology

At present, most of the radiating units used in TD-LTE antennas are die-casting. Although the performance of the die-casting radiating unit can already meet the requirements of the TD-LTE antenna, the die-casting radiating unit also has the advantages of large volume and heavy weight. characteristics, it poses a challenge to the transport of the antenna to the station, and it is also not conducive to the miniaturization of the antenna machine; it greatly increases the construction cost and subsequent maintenance costs of the base station

Embodiment 1

[0040] like figure 1 It is the overall structure diagram of the front of Embodiment 1 of the present invention. There are four polygonal metal sheets (1) on the front and back sides of the PCB dielectric board (16) to form two sets of mutually orthogonal half-wave oscillators ( figure 2 is the front structure of the radiator, image 3 is the opposite structure of the radiator); one arm of each group of half-wave oscillators has a metallized via hole (2), which allows the tin-plated metal base (9) to pass through the radiator smoothly, and the radiator Support; openings (3) are left on each polygonal metal sheet (1), and the opening treatment is mainly to adjust the impedance of the radiation unit; metallized via holes (4) are left at the ends of the polygonal metal sheets (1), and the metal The via hole (4) can not only ensure that the tinned metal sinker column (8) passes through the radiator vertically, but also enable the polygonal metal sheets on the upper and lower sur...

Embodiment 2

[0051] Figure 8 It is the overall structure diagram of Embodiment 2 of the present invention. The metal radiation sheet (1) in Embodiment 2 changes from a hexagon with holes to a stepped zigzag; this structure is also sufficient to work at 1880 MHz-2690 MHz frequency range. Embodiment 2 illustrates that the radiator in the present invention can have various implementation forms.

Abstract

The invention discloses a miniaturized wideband radiating element suitable for TD-LTE antennas. The miniaturized wideband radiating element comprises radiating bodies which are printed on the front face and the back face of a PCB dielectric slab (16) respectively, a sinking column (8) for regulating the low-frequency standing wave ratio and the cross polarization ratio, a tin-plated metal base (9) and coaxial cables (10). The radiating bodies are composed of metal sheets of double-layer structures and feed pieces which are vertically separated. On the premise of guaranteeing the bandwidth of the antennas, the overall weight and size of the antennas can be greatly reduced, and a base station can be conveniently built and maintained in later periods. Compared with a current metal die-casting radiating element, the miniaturized wideband radiating element can be more easily welded and assembled, and is better in stability.

Description

technical field [0001] The invention relates to a miniaturized broadband radiation unit suitable for TD-LTE antenna, and the radiation unit can work in the frequency range of 1880 MHz-2690 MHz. technical background [0002] With the continuous maturity of 4G technology and the country's continuous promotion of 4G, 4G technology will soon be popularized in China. In addition, in order to restore its decline in 3G, China Mobile has vigorously promoted 4G technology to the market since 2012. By the end of 2012, China Mobile had completed the construction of 20,000 base stations in several major cities in China, and realized the 4G network. commercial trials. In 2013, China Mobile continued to make efforts in 4G, and built the world's first integrated TD-LTE and LTE-FDD network in Hong Kong. In order to compete with China Mobile, China Unicom and China Telecom have successively carried out the construction of 4G test network, and the investment is gradually increasing. With t...
