Problems solved by technology

Given that domestic operators have included 700MHz as the main golden construction frequency band for 5G construction, antennas with this structure cannot meet the demand for 700MHz in the golden construction frequency band of 5G networks on the one hand, and lack the coverage of the 3300-3800MHz frequency band on the other hand.

Embodiment 1

[0026] like figure 1 As shown, the present invention provides a tri-band miniaturized and beautified building antenna 100 including a housing 1 and an antenna body 2 installed in the housing 1, and the antenna body 2 can perform ±30° in the housing 1 with the long side of the housing 1 as the axis. ° rotation; so as to meet the coverage requirements of special scenes, so that the product maintains good coverage performance.

[0027] like figure 2 As shown, the antenna body 2 includes a reflector 20 and a low frequency array 21, an intermediate frequency array 22, a high frequency array 23 and a spacer 24 arranged between two adjacent arrays mounted on the reflector 20; the low frequency array 21 is arranged On one side of the long side of the reflector 20, the intermediate frequency array 22 and the high frequency array 23 are arranged along the same center line on the other side of the long side of the reflector 20, so that the low frequency array 21 is not affected by the ...

Embodiment 2

[0038] The main difference between the second embodiment and the first embodiment is that the high-frequency differential feed line 2316 is a high-frequency differential feed line with a positive and negative 45-degree dual polarization, which are respectively a positive polarized high-frequency differential feed line and a negative polarized high-frequency differential feed line. Frequency differential feed line. like Figure 5 As shown, four high-frequency feed pins 2318 are provided to be connected to the positively polarized high-frequency differential feed line and the negatively polarized high-frequency differential feed line, respectively. The high-frequency differential feed line with positive and negative 45-degree dual polarization feeds the high-frequency radiation sheet 2312 through four high-frequency feed needles 2318, and transmits the high-frequency current of the positive and negative electrodes to the high-frequency radiation sheet 2312. The frequency radiat...

Abstract

The invention relates to a three-frequency miniaturized building beautifying antenna, which comprises an outer cover and an antenna body arranged in the outer cover, and is characterized in that the antenna body comprises a reflecting plate, a low-frequency array, an intermediate-frequency array, a high-frequency array and an isolating bar arranged between every two adjacent arrays, and the low-frequency array, the intermediate-frequency array and the high-frequency array are arranged on the reflecting plate; the antenna body rotates by + / -30 degrees in the outer cover by taking the long side of the outer cover as an axis; the low-frequency array is arranged on one side of the long edge of the reflecting plate, and the intermediate-frequency array and the high-frequency array are arranged on the other side of the long edge of the reflecting plate along the same center line; the distance between two adjacent intermediate-frequency radiation units in the intermediate-frequency array and the distance between two adjacent low-frequency radiation units in the low-frequency array are respectively 2 times and 4 times of the distance between two adjacent high-frequency radiation units in the high-frequency array; and at least one intermediate-frequency radiation unit and one high-frequency radiation unit are axially nested to form an integrated radiation unit. The antenna provided by the invention is miniaturized in size, has good gain index, radiation performance and coverage performance, and realizes frequency band coverage of 690-960 MHz, 1700-2700 MHz and 3300-3800 MHz.

Description

【Technical field】 [0001] The present invention relates to the technical field of mobile communication, and more particularly, to a tri-band miniaturized and beautified building antenna. 【Background technique】 [0002] With the requirements of urban construction for beautifying the environment, beautifying building antennas are being widely promoted and used. Building antenna is a kind of mobile communication system antenna, which is mainly used for indoor signal coverage and signal enhancement of buildings. In view of the current domestic network construction ideas, the coexistence of 2G, 3G, 4G, and 5G in the next few years has been unanimously recognized by the industry. Therefore, it is necessary to realize the sharing of a single antenna in a variety of different frequency bands to meet the needs of communication; Antennas can also reduce the number of antennas. [0003] In the existing multi-band antennas that can cover 698-960MHz, 1710-2700MHz, and 3300-3800MHz, in o...
