Abstract


An integrated antenna diversity system is described which enables a high increase of reception performance for satellite digital audio radio services (SDARS). A detailed analysis is given for the gain and noise figure requirements specifically regarding the implementation in an integrated circuit. In this contribution a compact integrated diversity system is specified and its realization is described. Also sufficient immunity to high level interferers must be ensured which can be in close proximity as far as frequency distance is concerned. On base of the specified values the system provides an overall gain of 26.8 dB with a noise figure of 0.84 dB including the single rf cable connecting the diversity antenna set to the unmodified standard SDARS receiver. A hardware demonstrator of our scan-phase antenna diversity system is presented in which the phase aligned rf combining and signal selection is implemented in a compact IC with a package size of only 8mm by 8 mm. Measurement results with recorded Rayleigh fading signals from a test drive in the US with a duration of 290 s show a reduction of audio mutes from 29.8 s of the best single antenna to only 4.1 s with our scan-phase antenna diversity demonstrator.
