Problems solved by technology

The smart antennas currently used are all area array smart antennas. The antenna scans its beam in the horizontal plane by changing the amplitude and phase parameters of the array unit. However, the gain of the area array smart antenna decreases rapidly when the scanning angle is large, and because The relative size is relatively large, and it takes up a lot of space when installed outdoors, and the installation is relatively cumbersome

Embodiment Construction

[0018] See figure 1 with figure 2 , The present invention relates to a smart antenna. The antenna includes an antenna support 3, the antenna support 3 is a cylindrical structure, and a plurality of antenna element arrays 1 are uniformly arranged around the antenna support 3, and a plurality of antenna element arrays 1 is surrounded by a cylindrical structure concentric with the antenna support 3, a fixing member 4 is connected between the antenna element array 1 and the antenna support 3, and a coupling disk 2 is sleeved on the antenna support 3.

[0019] The following compares the antenna element array of the present invention with a conventional four-column planar array when it is 12:

[0020] By comparison Figure 4 with image 3 The maximum level value, the maximum level difference is within 1dB, Figure 4 The width of the corresponding service beam pattern can be arbitrarily designed between 25° and 35°, and the control of the service beam can be determined according to the co...

Abstract

The invention relates to an intelligent antenna which comprises an antenna support frame (3). The antenna support frame (3) is of a cylindrical structure; a plurality of antenna unit arrays (1) are uniformly arranged around the antenna support frame (3) and enclose into a cylinder structure concentric to the antenna support frame (3); and a fixed part (4) is connected with between the antenna unit array (1) and the antenna support frame (3). The intelligent antenna has the beneficial effects that on the premise of not changing the existing hardware system, not only can the various performances of the intelligent antenna be ensured, but also the effect of keeping the gain unchanged in the wave beam scanning can be realized; and moreover, the installation is convenient, and the occupied space is small.

Description

(1) Technical field [0001] The present invention relates to an antenna, in particular to a sectorless smart antenna used in wireless communication. (2) Background technology [0002] Mobile communication 3G standards mainly include TD-SCDMA, WCDMA, CDMA2000, and WiMax. The TD-SCDMA standard is a standard proposed and vigorously promoted by China, which is widely used in China. Smart antennas are the main technology of TD-SCDMA. One of the characteristics. The smart antennas currently in use are all area array smart antennas. The antenna realizes its beam scanning in the horizontal plane by changing the amplitude and phase parameters of the array unit. However, the gain of the area array smart antenna decreases quickly when the scan angle is large, and due to the area array Relatively large in size, it occupies a large space for outdoor installation, and the installation is more cumbersome. (3) Summary of the invention [0003] The purpose of the present invention is to overcome ...
