ABSTRACT
ABSTRACT:
Substrate Integrated Waveguide (SIW) is a new type of transmission line for transmitting electromagnetic waves. In this new technology, a waveguide structure is implemented on a piece of printed circuit board (PCB) and its side walls are replaced by two rows of metal posts. Inheriting low radiation loss, acceptable Q-factor and high power handling capability from traditional rectangular waveguide structures, SIW also utilizes low cost, low profile and easy integration capabilities of planar structures, and thus opens another door to designing efficient microwave circuits and antennas at a low cost.
As SIW structures are planar realization of traditional rectangular waveguides, electrical behavior of these structures are very similar to rectangular waveguides, but only a reduced set of modes (TEm0 modes) can exist in these structures. Thus, modal analysis techniques are a proper choice for investigating the behavior of these structures. In this presentation, the Mode Matching Technique (MMT) as one of these modal analysis techniques will be described and different SIW structures analyzed by this method will be presented.
