contents Antenna performance enhancement using inter-coupling effect reducing mechanisms Gebrehiwet Gebrekrstos Lema Ingeniería side lobe beamforming directivity Antenna design Recently, thinning an antenna has resulted in attractive antenna radiation characteristics enhancement. This performance enhancement using a thin antenna array is achieved because the inter-coupling effects of the array elements are reduced. Though the thinning both reduces the weight of the antenna and enhances the radiation characteristics, iterative algorithms can further enhance the performance and hence, in this research, an optimizer algorithm and inter-coupling reducing mechanisms are applied. The excitation weights of the individual array elements are thinned by turning some of the elements off while some of the elements are turned on. The purpose of the thinning is to enhance the antenna performances like reduced SLL, high directivity, reduced power consumption and flexible radiation pattern. The SLL attenuation mechanism is applied to reduce the SLL in addition to the SLL reduction using the thinning and beamforming. Hence, in this paper, the three techniques (thinning, beamforming and SLL attenuation) are proposed to be integrated to enhance the antenna radiation characteristics. In general, the proposed combined method has resulted in much better SLL reduction, directivity improvement, and power wastage reduction. 2020 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47471672006 https://www.redalyc.org/journal/474/47471672006/ https://www.redalyc.org/journal/474/47471672006/html/ https://www.redalyc.org/journal/474/47471672006/47471672006.epub https://www.redalyc.org/journal/474/47471672006/movil 10.14482/INDES.30.1.303.661 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.18
