摘要： A vehicle includes: a location identification device to identify a location of the vehicle; a first antenna including an antenna body, a first feeding line connected to the antenna body, and a second feeding line including a phase delay device connected to the antenna body; a first wireless transceiver connected to the first antenna to provide a communication signal to the first antenna through the first feeding line or the second feeding line; and a controller. The controller is configured to control the first wireless transceiver to provide a communication signal to the first antenna through the first feeding line in a first communication mode, control the first wireless transceiver to provide a communication signal to the first antenna through the first feeding line and the second feeding line in a second communication mode, and switch to the second communication mode if the vehicle approaches a toll booth while operating in the first communication mode.
