A system with one or more transceiver antenna assemblies for installation in vehicle side-view mirrors to enable communication with nearby vehicles. Each transceiver antenna assembly may have one or two antenna arrays implemented on a single printed circuit board, protected by an antenna housing used to mount the transceiver antenna inside the mirror assembly. Each antenna array in a dual-channel transceiver antenna may transmit and receive data over one of two DSRC channels. One channel may be used to transmit and receive vehicle data only and the other channel may be used to transmit and receive both vehicle data and audio/video (A/V) data. Each antenna array is connected to a radio in the vehicle that processes received signals and prepares signals for transmission. Such a transceiver antenna system may be especially useful for communication in truck platooning.
