“…All these factors contributed to form a special EBG pixel with an original radiating surface which gives the matrix many EM advantages in comparison with an antenna array. We cite among them [3], the following: Low mutual coupling (below −20 dB for an inter-element spacing of λ 0 /2) Better conservation of the gain regardless the high scanning angle values (above 65°) High inter-elements distance allowed ( d ≥ λ 0 ), where low scanning angles are obtained (±10°) and no significant effect for the grating lobes [6] Better radiating surface efficiency Low cost and compact antenna technology. …”

Today's increase of functions, improvement of performances, and cost reductions required on an agile electronically scanned antenna, drive researchers to develop an innovative antennas’ concept in order to deal with the proposed challenge. In this context, this article describes and demonstrates an experimental prototype to show the reliability and efficiency of the electromagnetic band gap(EBG)matrix antenna theoretical aspect, for beam forming and beam steering applications. The originality of this work is the antenna itself which constitutes the subject of an accepted national and international patent. In fact, the proposed antenna is based on the equivalent radiating surface approach and used special EBG antennas called “pixels” to overcome some of the array approach defects. The antenna has demonstrated different electromagnetic behaviors, such as low mutual coupling, high gain preservation for high scanning angles values, etc.
