Abstract

An onboard unit (1) for wireless communication (2) with a vehicle identification system (3) via radio waves (W, W') comprises a housing (4) with a front side (5) and a rear side (6) and a circuit board (11) therein, an antenna (12) connected to the circuit board (11) and arranged in the housing (4) near the front side (5), and a solar cell (13) supported by the housing (4) near the rear side (6), powering the circuit board (11) and having a photosensitive side (15) and an electrically conductive layer (17), the photosensitive side (15) being visible from outside the housing (4), wherein the antenna (12) is arranged at a distance (D) from the electrically conductive layer (17) of the solar cell (13) such that radio waves (W) penetrating the front side (5) interfere at the antenna (12) with radio waves (W') reflected by the electrically conductive layer (17).
