Abstract: A vehicle antenna module is adapted to be assembled with a vehicle roof plate and includes a Telematics-Box and an antenna assembly. The Telematics-Box is fixed on the vehicle roof plate and includes at least one first sliding portion, at least one first latching portion and a first connector. The first sliding portion, the first latching portion and the first connector protrude out of at least one assembling hole in the vehicle roof plate. The antenna assembly is slidably arranged on the Telematics-Box, and the vehicle roof plate is located between the antenna assembly and the Telematics-Box. The antenna assembly includes at least one second sliding portion, at least one second latching portion and a second connector. When the second sliding portion slides along the first sliding portion, the second latching portion is latched to the first latching portion, and the second connector is electrically connected to the first connector.
