Abstract
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.
