Abstract： To improve the aesthetic integration of the vehicular communication system， a transparent multiband antenna with metal mesh was designed for seamless integration into transparent surfaces such as automotive glass. The antenna was fed by an asymmetric coplanar waveguide; the multiband characteristics were realized by bending and slotting the monopole structure， with overall dimensions of 100 mm × 40 mm × 1.1 mm. High optical transmittance was achieved through the use of a transparent metal mesh material and a transparent substrate. The measured results demonstrate good impedance matching across the operational bandwidth of the vehicular communication， with return loss below -10 dB and maximum gain of 4.9 dB， while the measured data closely match the simulation results. The antenna is characterized by simple structure and high transmittance， and has a wide range of application scenarios in the field of automotive systems.
