Reference to Nearest Ground

Reference to Nearest Ground

When you setup excitations using the Edge Port Definition dialog, you can choose to select the Reference option and specify the nearest ground. This option explicitly forces the reference of a port to be located on the nearest ground plane, directly below (or above) the port. A vertical trace connecting the port to its reference is added to the structure.

The Reference to a nearest ground option should be used when the port is over one-tenth of a wavelength from the ground plane. If the port is closer than one-tenth of a wavelength, referencing to the nearest ground is unnecessary.

Warning

In a stripline environment, the additional vertical current that results from using the Reference option to the nearest ground may excite the parallel plate mode — which could create inaccurate results.
