Abstract

The invention relates to the technical field of communication antennas, and specifically discloses a lens miniaturized antenna, which includes an antenna radiation unit, a reflector, a cylindrical lens, a fixing plate and an antenna cover; the fixing plate includes an upper fixing plate connected above the antenna cover and Connected to the lower fixed plate below the antenna cover; the reflector is movably connected between the upper fixed plate and the lower fixed plate; the cylindrical lens is located in the antenna cover and fixed laterally between the upper fixed plate and the lower fixed plate; The antenna radiating unit is fixedly installed on the reflector, and the radiating surface of the antenna radiating unit faces the cylindrical lens; the horizontal wave width of the antenna radiating unit is kept constant through the horizontally placed cylindrical lens, and the vertical wave width is compressed to achieve high secondary Lobe suppression can achieve the effect of multi-element array, and at the same time, it can realize large-angle electric adjustment downtilt, reduce the size of the antenna, reduce the cost of the antenna, effectively realize the miniaturization of the base station antenna, and also reduce the cost of labor installation.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a lens miniaturized antenna. Background technique [0002] With the development of the base station industry, base station antennas tend to be smaller and lighter. At present, domestic base stations mostly use multi-antenna unit arrays to meet the needs of regional signal coverage. Array elements are arranged more densely in a limited space. [0003] At present, domestic macro base station antennas generally use vertical multi-element arrays to compress the vertical lobe width, thereby increasing the radiation gain of the antenna and obtaining better sidelobe suppression; however, multi-element arrays are bulky and difficult to install. [0004] In view of this, the present invention proposes a new base station antenna scheme with a single radiating unit combined with a cylindrical lens, which has high sidelobe suppression while obtaining high gain. Compared with ...
