摘要：A waveguide structure including two parallels electrically conducting groundplanes (), each of which includes at least one row of spaced apart electrically conducting
posts (). The rows of posts are arranged substantially parallel to one another and thespace bounded by the plates and posts defines a guided wave region () along whichelectromagnetic radiation may propagate. The posts are connected to only one of theplanes so that there is no physical connection between the two ground planes ().Actuating means may be connected to one or both of the ground planes to causerelative movement there between to thereby alter the electrical response of thewaveguide. The direction of the relative movement may such that the distance betweenthe rows of posts () is changed and/or the distance between the ground planes () ischanged. Various device may utilize the described waveguide construction, includingreconfigurable waveguide filters and antenna structures e.g. slotted waveguide arrays.
