    摘要: A digital tacho graph (DTG) apparatus for vehicles is disclosed. The DTG apparatus includes a metal terminal having one end connected to a printed circuit board (PCB) pattern unit connected to the wireless communication module, an RF antenna embedded inside the DTG apparatus and having one end connected to the other end of the metal terminal, and a front case unit, on which the other end of the RF antenna is formed by patterning, the front case unit serving as a front case of the DTG apparatus and enclosing the RF antenna inside the DTG apparatus. The wireless communication module and the embedded RF antenna are integrated, thereby reducing working time, increasing transmission and reception sensitivity, and reducing cost.
