<P>PROBLEM TO BE SOLVED: To reduce propagation loss at a wide range of frequencies by replacing a microstrip line (MSL), whose loss increases with frequencies, by a dielectric waveguide. <P>SOLUTION: A system for inter-chip RF communication is mounted on a PCB, and has a dielectric waveguide 22 made of a dielectric material. The system has couplers 24, 26 at respective ends 32, 34 of the dielectric waveguide 22. The couplers 24, 26 couple the dielectric waveguide 22 with signal sources 28, 30, respectively. The dielectric waveguide 22 is, on the PCB, printed, embossed, cut or pre-prepared. <P>COPYRIGHT: (C)2013,JPO&INPIT |
