Optimization of the antenna-diversity-effectiveness of complex FM-car-antenna systems

Abstract

A criterion for the diversity effectiveness of a multi-antenna arrangement on a car is derived. This number of equivalent decorrelated antennas being effective is evaluated by turntable antenna measurements as a basis for computer simulated virtual drives in a Rayleigh wave propagation scenario. The comparison of a variety of antenna arrangements shows that even compact antenna systems on a car window provide high diversity effectiveness.
