In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Generally, after the vehicle-mounted antenna is assembled in a sealed manner, a sealed space is formed inside the vehicle-mounted antenna, so that the air pressure inside and outside the antenna cannot be adjusted, and when negative pressure exists in the sealed space due to severe changes of the external environment, the sealing effect of the vehicle-mounted antenna is affected. The fact that negative pressure exists in the sealed space means that due to the influence of extreme conditions and environments, the air pressure of the sealed space of the vehicle-mounted antenna is far lower than the external atmospheric pressure, and at this time, because the external atmospheric pressure is higher than the air pressure of the sealed space of the vehicle-mounted antenna, water accumulation or water stain leakage towards the negative pressure direction (namely, the internal space of the vehicle-mounted antenna) may be caused under the action of the external atmospheric pressure, so that the antenna body is subjected to waterproof failure.

As shown in fig. 1, an embodiment of the present invention provides a vehicle-mounted antenna, including: the antenna comprises a shell 1, a waterproof and breathable structure 4 and an antenna base 3; wherein, the antenna base 3 is partially disposed in the housing 1 and is hermetically connected with the housing 1, i.e. the antenna base 3 is partially sealed in the housing 1 and partially exposed outside the housing 1.
