Experimental evaluation of a hybrid substrate integrated waveguide

A hybrid substrate integrated waveguide is investigated for high-speed data transmission. A hybrid prototype is fabricated and evaluated experimentally. From frequency-domain characterization, the SIW is shown to provide higher bandwidth than that of the embedded stripline interconnect. Wideband system components, i.e., mixers and lowpass filter, are incorporated to enable very high-speed signaling. Measurement of the hybrid system demonstrates achieving excellent transmission quality at the aggregate data rate of 20 Gb/s.
