                         microstrip antenna arrays is presented in this paper. The novel 
                         concept consists in the design of the radiators asymmetrically 
                         positioned with respect to the ground plane. In order to validate 
                         this technique, a four-element linearly-polarized array is 
                         designed in the HFSS software and a prototype is manufactured. 
                         Furthermore, the design of beamforming circuit to achieve 
                         broadside radiation and -20 dB side lobe level is detailed. Very 
                         good agreement between simulated and experimental results is 
                         obtained. Although the technique is presented for linearly 
                         polarized arrays, it is general and can also be applied in the 
                         circularly polarized ones.",
