The reinforcing ribs 25 and the shield frame 40 distributed in the array enhance the strength of the vibrator part 20 And flatness, to ensure the strength of the whole machine without the reflector. When assembling, the filter 30 is connected and fixed to the second metal layer 11 of the calibration network board 10 in the form of an array distribution by welding such as SMT, and then the filter 30 fixed on the calibration network board 10 is installed to the vibrator part 20 In the shielding frame 40, the vibrator part 20 is provided with a fixing pin 24 to facilitate the positioning of the calibration network board 10. Finally, the metal feed core 23 is welded to the feed hole 13 on the network calibration board 10 to achieve electrical connection, and the screws 60 are used to connect the The vibrator part 20 and the calibration network board 10 are fixed together to complete the assembly.
借此，本发明通过将滤波器30设置于校准网络板10和振子部20之间，并利用一体化注塑成型的特点直接设计出代替屏蔽腔的屏蔽框40结构，一方面降低了天线模组100厚度易于小型化，另一方面省略了反射板和滤波器屏蔽腔，并大幅降低重量和成本。Therefore, the present invention directly designs the structure of the shield frame 40 instead of the shield cavity by arranging the filter 30 between the calibration network board 10 and the vibrator part 20 and using the characteristics of integrated injection molding to directly design the structure of the shield frame 40 instead of the shield cavity. On the one hand, the antenna module is reduced. The thickness of 100 is easy to be miniaturized. On the other hand, the reflector and filter shielding cavity are omitted, and the weight and cost are greatly reduced.
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。The above are only the embodiments of the present invention. It should be pointed out here that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present invention, but these all belong to the present invention. The scope of protection.
