Abstract
The diversity effectiveness represents the signal improvement by means of an antenna diversity arrangement expressed by an equivalent fictitious number of n decorrelated antennas. With a low-cost compact 4antenna-arrangement on the backlite the diversity effectiveness is considerably higher than with a 2antenna-system with one antenna on each of the front and the back window. This is evaluated from antenna measurements and computer simulation of a Rayleigh field. Further antenna arrangements are discussed. Complex antenna systems of this kind for FM-TV-antenna diversity and AM radio require a device for selftesting of operating functions for OEM production and customer service as well.
