A method and an apparatus are provided for providing a tunable substrate integrated waveguide (SIW) for which a parameter of at least some element or portion thereof may be altered or varied to alter the propagation of a signal propagating through the SIW thereby achieving a tunable SIW. In some embodiments a plurality of capacitively variably loaded transverse slots achieve the tunability for the SIW.

Tunable substrate integrated waveguide components

The present invention relates to a method and system for high-speed bandpass serial data communication. A driver receives at least one data signal and generates a bandpass data signal for transmission through a bandpass waveguide interconnect. The bandpass data signal is launched into the bandpass waveguide interconnect using a first adaptor and extracted therefrom after transmission using a second adaptor. A receiver connected to the second adaptor recovers the at least one data signal from the extracted bandpass data signal. A dispersion compensation circuit receives one of the at least one data signal and the bandpass data signal and information indicative of a phase response of the bandpass waveguide interconnect and dispersion compensates the one of the at least one data signal and the bandpass data signal by compensating the phase response of the bandpass waveguide interconnect.
