Car Windshield Antenna Effect on a Cable Harness

Application ID: 16965

Modern cars have rear-windshield FM antennas to play FM radio. The radiation emitted from an antenna induces an electric current on the outer surface of any cable harnesses in the car, which can have negative effects.

This model uses the RF Module to compute the far-field radiation pattern of the antenna, by enclosing the car in perfectly matched layers separated by an air domain. The electric fields on the interior cable harness show which sections are more affected by the antenna radiation.

This model example illustrates applications of this type that would nominally be built using the following products:
