ABSTRACT:
A compact wide-band panel antenna is modified to provide a dual-mode antenna system with improved operation, particularly in the presence of interfering signals and varying reception conditions in mobile communications applications. A hybrid junction arrangement is used to combine received signals in sum and difference modes suitable for adaptive processing. Signal transmission is provided by reciprocal operation, with a circulator incorporated for signal isolation. The dual mode capability provides previously unavailable performance in a small, economical broad-band antenna.
