ANTENNA DIVERSITY RECEIVER ARRAY AND METHOD OF SELECTING AN ANTENNA FROM A PLURALITY OF ANTENNAS

摘要

The invention relates to an antenna diversity receiver array and a method of selecting an antenna from a plurality of antennas (1a, 1b, 1c) of this array. The selected antenna is then coupled to a (main) receiver unit (2a) via a change-over switch (5a). According to the invention a background receiver unit (2b) is provided which is cyclically connected to the antennas (1a, 1b, 1c) via a second change-over switch (5b) and continuously monitors their signal strength. A control unit (6) can then detect the antenna that has the best signal strength and couple this to the receiver unit (2a) via the first change-over switch (5a). Also forecasts about the variation of the signal strengths can then be taken into account.
