Abstract :
Surface waves, especially the fundamental substrate-guided TM0z mode, are excited by any kind of discontinuity in RF printed circuit boards (PCBs) and planar microwave circuits. This special type of substrate-bound radiation is highly increasing with frequency and can become a dominant coupling mechanism in planar circuits. In this paper, an efficient method is presented to calculate correctly the coupling mechanism by surface wave radiation. The required current distribution is estimated only with single-port CAD models.
