They are very low-cost in comparison to the classic milled metallic waveguides as they may be developed using inexpensive printed circuit board (PCB) fabrication techniques.

Among these are the substrate integrated waveguides (SIWs), initially introduced as laminated waveguides [1, 2], that can be easily implemented using common printed circuit board (PCB) fabrication methods.
Various types of SIW power dividers, couplers, and diplexers have been designed and optimized for operation at microwave and mm-wave frequency bands using PCB substrates [15-23].
