Study of Adaptative V-Band Channels Allowing Broadcast and Point to Point Communications in the WiNoC Concept

This paper proposes to design V-band adaptive channels for wireless network-on-chip (WiNoC) communications. The aim is to optimize point-to-point or broadcast communications, considering a parallel plate propagation medium. First, reflectors are introduced and simulated on a high-resistivity silicon substrate (HR-Si) surrounded by a low-resistivity silicon (LR-Si) layer obtained by doping. The polarization of the reflectors improves the bandwidth for slot antennas located 45° apart, increasing it from 1.5 GHz to 11.1 GHz. Another transition method, CPW-SIW transitions, is then used to enable point-to-point or broadcast transmissions, depending on the reflector's resistivity. These transitions also improve the initial solution in terms of transmission levels by more than 6 dB without active reflectors. In simulations, transmission levels of -4.8 dB with a bandwidth of 21 GHz are achieved, making it possible to reach data rates of 18 Gbit/s.
