Abstract:
A sheet metal waveguide includes a pair of sheet metal channels with each channel having a double bend or fold along each of two substantially parallel leg sections. The channels are arranged relative to each other such that a portion of a leg suction of one channel overlaps a portion of a leg section of the other channel in a manner to form a waveguide having recesses on opposite broad walls thereof suitable for receiving and holding a dielectric body therebetween. The ends of the leg sections of one channel are clipped and thereby held within a bend or fold in the leg sections of the other channel.
