ABSTRACT:
To isolate adjacent elements of an antenna array from each other, each feeder contains a power divider with four terminals, two of which are connected to the power dividers associated with the adjacent elements. The power dividers feed r.f. energy to the inactive elements in such a way that the latter no longer act as parasitic elements. The r.f. power dividers are so designed that three is a mismatch when looking from the antenna toward the power divider. This gives a further improvement in the isolation between adjacent antennas.
