Severalconcepts of antenna diversity for satellite digital audio radio systems (SDARS) are investigated. Acomparison is made regarding the improvement of reception quality.Special attention is paid to easy realisation in an automotive environment. Proof is shown that for critical reception scenarios for example underneath dense foliage or in multipath situations between high buildings an antenna diversity system yields asignificant reduction of the total duration of mutes. The concept of anew scan diversity and a combined scan/phase antenna diversity system are investigated, realised in hardwareand evaluated in real scenarios. Full diversityfunction is achieved with only minor or even without modifications of the receiver and no additional effort in mounting and required space for the antenna modules.Asinsingle arm reception systems only one tuner is used. There is only one antenna cable between antenna module and the receiver.
