[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figures 1 to 3 As shown, a full-band antenna includes a bracket 1, a first FPC antenna 2, a second FPC antenna 5, a conductive foam 4 and a terminal wire 3.

[0021] The terminal wire 3 is welded on the first FPC antenna 2 . The bracket 1 has a top surface, a bottom surface and at least two side surfaces. The bracket 1 is in a square cap-shaped structure as a whole.

[0022] The first FPC antenna 2 is laid on the top surface of the bracket 1, and the second FPC antenna 5 is laid on the bottom surface of the bracket 1. The first FPC antenna 2 is connected to the second FPC antenna 5, and the second FPC antenna 5 is connected to the ground of the mainboard through the conductive foam 4. The ground of the mainboard adopts a copper-exposed pad, and the conductive foam 4 is attached to the copper-exposed pad. The mainboard is the main control board installed on the product.

[0023] The bracket 1 is an insulating bracket, preferably a plastic bracket.

[0024] The first FPC antenna 2 is provided with a ground pad and a feeding pad, and the terminal wires 3 are respectively welded on the ground pad and the feeding pad.

[0025] The terminal wire 3 is plug-connected to the port of the mainboard.

[0026] The second FPC antenna 5 is provided with a gold-plated portion, and the conductive foam 4 is connected to the gold-plated portion.

[0027] The utility model provides a full-band antenna, which adopts a combination structure of a bracket, a first FPC antenna, a second FPC antenna, a conductive foam and a terminal wire. The antenna is connected to the mainboard ground through the conductive foam 4, and then the terminal wire 3 is welded, and then the terminal wire 3 is buckled on the mainboard to form conduction, thereby achieving the requirements of small antenna space and high performance, so that the antenna can meet the performance of LTE.

[0028] The utility model provides a full-band antenna that can increase the antenna bandwidth to meet the low-frequency 698-960Mhz, high-frequency 1710-2690 / 3300 4200MHZ 4G full network and 5G antenna band performance requirements. The device is suitable for CPE equipment where there is no clearance for the antenna and only the height of the bracket. The antenna is connected to the mainboard through conductive foam 4 and then soldered with terminal wires 3, so that the antenna can better meet the performance of 4G and 5G.

[0029] The utility model is designed based on the situation that the antenna space is small and there is no clearance and the performance requirements are high. The size of the wiring on the bracket is not enough to achieve the performance required by 4G 5G. Therefore, a combination of a bracket, a first FPC antenna, a second FPC antenna, conductive foam and terminal wires is adopted. The antenna bandwidth and efficiency can be improved through the ground of the motherboard, thereby meeting customer performance requirements.
