Performances of Magneto-Electric Dipoles in an Antennas Array with a Reduced Beam Forming Network

International audienceIn this paper, we propose an architecture of array based on parasitic element antennas with multiple excitations. The objective is to improve the directivity of these antenna arrays using Magneto-Electric Dipoles (MED). In this contribution, we consider a 49 (7 X 7) element array with only 8% of the elements directly fed. The others are fed by couplings and they are loaded on reactive values (ideally). The proposed radiating element is compared to a stacked patch design in the same reduced feed network configuration. A maximum directivity of 20 dBi is obtained, allowing several reconfigurable antenna scenarios based on such as design
