Problems solved by technology

However, the corresponding sky resources are more tense, and it becomes inappropriate to use multiple discrete antennas of different standards. Not only is it not harmonious with the surrounding environment, but also the load-bearing requirements for the tower mast are very strict.

Abstract

The invention discloses an ultra-wideband dual-polarization radiation unit. The ultra-wideband dual-polarization radiation unit comprises a Balun structure, a radiation arm assembly, two feeding pieces, a plastic support piece and a parasitic radiation sheet, wherein the Balun structure is arranged at the bottom of the unit, the radiation arm assembly is arranged at a top end of the Balun structure, the parasitic radiation sheet is arranged above the radiation arm assembly by the plastic support piece, the two feeding pieces are inserted into the Balun structure, and top ends of the two feeding pieces are connected with the plastic support piece. The radiation unit employs a special loading structure and the parasitic radiation sheet and has the characteristics of wide impedance bandwidth,stable 3dB power lobe width, high grain and good polarization isolation.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to a radiation unit applied to an ultra-wideband dual-polarization base station antenna in which multiple systems coexist. Background technique [0002] With the continuous increase of mobile communication standards, the range of frequency bands used by wireless networks is also becoming wider and wider. However, the corresponding sky resources are more tense, and it becomes inappropriate to use multiple discrete antennas of different standards, which not only cannot be harmoniously unified with the surrounding environment, but also has very strict load-bearing requirements for the tower mast. Ultra-wideband antennas can solve the contradiction between the two very well, especially with the widespread commercial use of 4G networks, the demand for broadband antennas is very common, and the antenna products on the market are also broadband antennas. The basis...
