MULTIPLE ANTENNAE ARRANGEMENTS COUPLED VIA A POWER DIVIDER TO PROVIDE DIRECTIONAL AND/OR OMNI-DIRECTIONAL CHARACTERISTICS

摘要

The invention relates to an arrangement of at least two antennas (A1, A2) with directional and/or omnidirectional characteristics, coupled via a power divider (1), in particular for a mobile radio system with two antennas arranged spatially back to back with respect to one another. In the case of such an arrangement, it is intended that a radiation characteristic free of null points will be produced. To this end, the invention provides, in the feed path of one antenna (A2), a phase shifting network (2) of such a type that an interference-free radiation characteristic is produced (Figure 2). IMAGE
