With rapid technological advancements, many new technologies and communication protocols have emerged, such as Wi-Fi 5, Wi-Fi 6, and 5G, resulting in a wide variety of antennas used in wireless communication products. Currently available patch antennas have a linear, unidirectional radiation direction with dead zones, making signal propagation prone to interruptions. Furthermore, the existing patch antenna architecture is simple, and the radiated energy is easily attracted by surrounding components, leading to positional shifts. (Utility Model Content) The technical problem to be solved by this utility model is how to provide a 3D omnidirectional diffused angle spiral antenna that is easy to install, has a more complete radiated energy direction, and better signal propagation quality.

[0004] A further technical solution is that the spiral metal structure includes a front metal unit and a back metal unit, and the front metal unit and the back metal unit are connected by a metallized via penetrating the dielectric layer.

[0005] A further technical solution is that the front metal unit is located on the front side of the dielectric layer, including several first metal layers horizontally arranged between the flared metal structure and the pad structure.

[0006] Preferably, the first metal layer has three layers.

[0008] Preferably, the second metal layer has two layers.

[0009] A further technical solution is that the first metal layer and the second metal layer are connected together through the metallized via, so that the front metal unit and the back metal unit are spiral in shape.

[0010] A further technical solution is that the horn-mouth metal structure includes a front horn-mouth unit and a back horn-mouth unit, the openings of the front horn-mouth unit and the back horn-mouth unit face upwards, and the two are connected by metallized through holes.

[0011] A further technical solution is that the pad structure includes a left pad unit and a right pad unit, the left pad unit and the right pad unit are U-shaped in whole, and one end of the left pad unit or the right pad unit is connected to the lower end of the spiral metal structure.

[0012] The beneficial effects of adopting the above technical solution are as follows: The antenna described in this application has a two-part structure, with a lower spiral structure and an upper horn structure, which enables energy to be concentrated and emitted in all directions, resulting in a more complete radiation energy direction and better signal propagation quality. The surface-mount 3D structure can be directly and automatically SMT onto the PCB board, making installation convenient. Attached Figure Description
