—This paper presents the possibilities of radio transmission realizations around the frequency of 45 GHz for wireless communication networks in a " Printed Circuit Board " (PCB) context. First, we present transmission measurement results between two dipole antennas on a multilayer PCB circuit in the 40-50 GHz bandwidth. We also study the effect of metallic obstacles (grid, checkerboard) between our antennas on the same structure. Secondly, from these measurements, we evaluate the expected transmission performances of the propagation channel of our system. In particular, we present the eye diagram simulation results for several configurations and we show that our system is able to achieve data rates of about 2 Gbit/s.
