Wireless interconnects by using printed antennas for inter-chip communications in PCB context

This paper presents an implementation study of a wireless communication network in Printed Circuit Board (PCB) context. First, we point out the needs and the constraints in term of communication for a Wireless Interconnect Network-on-Board (WiNoB). Then, we present the electrical characteristics of the chosen dipole and “Vivaldi” antennas for the achievement of a 10 GHz demonstrator. Finally, using measurements and EM simulations, we evaluate the transmission between two antennas on a PCB substrate and we mainly present the results with Vivaldi antennas. We also study the effect on the transmission of various obstacles, as integrated components, lines, grids....
