Abstract: This paper compares two solutions for designing electronically agile beam antennas: the well-known AESA (Agile Electronically Scanned Arrays) approach and a new one called ARMA (Agile Radiating Matrix Antenna). This comparison is performed first on the electromagnetic principles of the two methods, and secondly on the performances in terms of bandwidth, radiation efficiency, coupling effects, side lobes, agility in beam forming and beam steering. Finally a validation of the new approach is performed by comparison of theoretical and experimental results.
