SlotlinePort Guidelines
Assume slot width is g
Assume dielectric height is h
Port Height:
Should be at least 4h, or 4g (larger). Remember to include air below the substrate as well as above! If ground plane is present, port should terminate at ground plane.
Port Width:
Should contain at least 3gto either side of slot, or 7g total minimum?Port boundary mustintersect both side ground planes, or they will ‘float’and become signal conductors relative to outline ‘ground’[/img]
