Low-profile radiating element and base station antenna

Abstract

The invention relates to the technical field of mobile communication equipment, and provides a low-profile radiating element and a base station antenna. The low-profile radiation element comprises a base and a plurality of direct radiation blocks, the base is provided with a plurality of support platforms in an extrusion mode towards the same direction, the plurality of direct radiation blocks arepressed and connected with the support platforms in a one-to-one correspondence mode, the lower surface of the base is provided with a micro-strip circuit in a laser etching mode, and the substrate is provided with a plurality of sliding buckles matched with a reflecting plate. Each direct radiation block comprises an injection molding body, and the two opposite sides of each injection molding body are respectively subjected to laser etching plating or full electric plating to form a direct surface and a radiation surface. According to the low-profile radiation element provided by the invention, the direct radiation blocks and the support platforms are pressed and connected with no need for welding operation; the sliding buckles are used to connect the base with the reflecting plate withno need for welding; the micro-strip circuit is subjected to laser etching at the lower surface of the base, the direct surface formed through laser etching plating or full electric plating improves the gain, a power division network is integrated, welding points are reduced to facilitate improvement of the manufacturing efficiency and reduction of the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a low-profile radiation unit and a base station antenna. Background technique [0002] With the advent of the 5G era and the trial commercial deployment of 5G networks, it marks that the integration of base station main equipment and large-scale array antennas will inevitably become a 5G communication trend. The demand for massive MIMO antennas will be much greater than that of traditional antennas. Higher and higher requirements for safety and low cost. [0003] At present, most commonly used 5G antenna radiation units are single oscillators, which are welded together with the PCB power distribution board, and then riveted with rivets, reflectors, and coupling boards to form a board. At the same time, the power distribution board and the coupling board also need to be welded. The welding of the entire single vibrator, the welding of the power division cou...
