[0025] like Figure 2 As shown, a high-strength road test unit receiving antenna includes a first PCB board 101 and two second PCB boards 102. The two first PCB boards 101 are parallel to each other, and the second PCB boards 102 are perpendicular to the first PCB boards 101 and fixedly connected between the two first PCB boards 101. Two support members are provided between the two first PCB boards 101. The support members have insertion slots 201. The direction perpendicular to the first PCB board 101 is the first direction. The two sides of the second PCB board 102 distributed along the first direction are respectively inserted into the insertion slots 201 of the two support members. Both ends of the support members are provided with limiting slots 209 that are inserted into the sides of the first PCB board 101. The two support members are fixedly connected by elastic fasteners 3.

[0026] The above antenna can be used for signal transceiving of a road test unit. In the antenna, two support members are respectively inserted on the two side edges of the second PCB board 102, and the two support members are connected by a fixing member 3. The elasticity of the fixing member 3 can apply a pulling force to the two support members to make the two support members tightly connected with the second PCB board 103, thereby improving the firmness of the support members. Meanwhile, the elastic fixing member 3 can adjust its length within a certain range, thereby adjusting the distance between the two support members, so that the support members can be applied to second PCB boards 102 of different sizes. The two end faces of the support members are respectively attached to the two first PCB boards 101, thereby playing a supporting and positioning role on the first PCB boards 101, so that the first PCB boards 101 and the second PCB board 102 can maintain a vertical state, thereby preventing the antenna from being deformed under external force. The limiting groove 209 is inserted into the side edge of the first PCB board 101, thereby achieving a further limiting effect on the first PCB board 101, so that the first PCB board 101 can bear a pulling force away from the second PCB board 102. The positioning and reinforcing effect between the first PCB board 101 and the second PCB board 102 is achieved by the support members, thereby improving the strength of the overall structure of the antenna, and further reducing the failure rate of the antenna.

[0027] In the above antenna, the positioning effect of the support members on the first PCB board 101 and the second PCB board 102 can also position the two boards before welding, thereby improving the welding precision and convenience between the two boards, and further improving the stability of the antenna signal transmission.

Secondly, the provision of the ventilation grooves 203 can reduce the material consumption of the ventilation member and reduce the production cost. The provision of the ventilation grooves 203 can also keep the air flowing on the surface of the second PCB board 102, thereby playing a heat dissipation role on the second PCB board 102, so as to improve the stability of the antenna signal transmission.

[0029] Further improvement is that, as shown in Figure 4 and 5 A plurality of ventilation holes 204 are uniformly distributed on the support members, and the ventilation holes 204 are communicated with the outside of the insertion slot 201 and the support members.

The positioning groove 205 can limit the fixing member 3, and the stability of the connection between the fixing member 3 and the support member is improved; and the antenna also has a signal line 103, and through the arrangement of the positioning groove 205, the signal line 103 can be wound inside the positioning groove 205, so that the antenna signal line 103 can be stored, and the convenience of the transportation of the antenna is improved.

[0032] Further improvement is, as shown in Figure 4 and 5 The outer edges of the two ends of the support member are provided with extension parts 206, the extension parts 206 are tightly combined with the first PCB board 101, and the extension parts 206 are uniformly distributed with a plurality of through holes 207.
