Potentialities of Reduced Beamforming Antennas using Magneto-Electric Dipoles

In 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 only fed by couplings and they are loaded on reactive values. The proposed radiating element is compared to a stacked patch in the same reduced array configuration. A maximum directivity of 20 dBi is obtained.
