Fig. 2 is the batch micro operations schematic diagram of the antenna assembly of the present invention.

A kind of optional embodiment as antenna assembly.

As shown in Fig. 2, the wireless communication module includes:Antenna assembly;The antenna assembly includes:Antenna substrate module (It is not shown in figure), conductive metal layer in antenna substrate module(111、112、114、115), be arranged in conductive metal layer Parasitic element 113 above;It is suitable for etching several opening void regions on the conductive metal layer;Opening void region it Between be equipped with parasitic element;And one layer of conductive metal film is covered on the surface of conductive metal layer and parasitic element.Specifically, At least four opening void region of setting, the parasitic element rank adjacent opening on conductive metal layer on conductive metal layer Between void region;The quantity of parasitic element is three, and the distance between parasitic element is equal, the dimensions length phase of parasitic element Together;Opening void region area between parasitic element is identical, the opening void region area being located at except parasitic element It can not wait.

Optionally, the conductive metal film is such as, but not limited to realized using plating mode.

The antenna substrate module can be the pcb board of routine, simply and reduce cost.

Multiple opening void regions are arranged in the antenna assembly of present embodiment on conductive metal layer, and it is traditional thread binding both to have reduced day The overall dimensions set, and greatly reduce production cost;Parasitic element is directly set on conductive metal layer, utilizes reasonable setting Size and position relationship, adjust parasitic element with opening void region superposition couple, realize the good increasing of antenna assembly Beneficial characteristic improves the communication quality of wireless communication module, to ensure that the information between monitor terminal and sub- photovoltaic devices Interaction fluency.
