The methodology here depicted is based on exploiting the nature of the continuous aperture distribution by expressing it as a Fourier series of moderately high orders. In this manner, the resulting illumination boundary is defined by a target three-dimensional flat-topped pattern composed of stretching and shrinking modified circular Taylor patterns and the maximum order of the series to obtain a good reconstruction is determined by means of the iterative process. Examples and comparisons with the previous literature were conducted by analyzing square and rectangular contoured beams as test cases. Additionally, interesting potentials regarding space applications from a geostationary satellite are outlined by means of the EuTELSAT (European Telecommunications Satellite Organization) European coverage case study. In such a way, its numerical approach was analyzed by including subarray architectures and discussing improvements about dynamic range ratio of the excitations without critical power losses within the illumination region.<\/jats:p>","DOI":"10.3390\/s21072358","type":"journal-article","created":{"date-parts":[[2021,3,28]],"date-time":"2021-03-28T23:27:25Z","timestamp":1616974045000},"page":"2358","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["An Improved Pattern Synthesis Iterative Method in Planar Arrays for Obtaining Efficient Footprints with Arbitrary Boundaries"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3408-3938","authenticated-orcid":false,"given":"Aar\u00f3n \u00c1ngel","family":"Salas-S\u00e1nchez","sequence":"first","affiliation":[{"name":"ELEDIA@UniTN, Department of Information Engineering and Computer Science (DISI), University of Trento, 38122 Trento, Italy"},{"name":"CRETUS Centre, Department of Applied Physics, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cibr\u00e1n","family":"L\u00f3pez-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"CRETUS Centre, Department of Applied Physics, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Antonio","family":"Rodr\u00edguez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"CRETUS Centre, Department of Applied Physics, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda Elena","family":"L\u00f3pez-Mart\u00edn","sequence":"additional","affiliation":[{"name":"CRETUS Centre, Department of Morphological Sciences, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5651-8883","authenticated-orcid":false,"given":"Francisco Jos\u00e9","family":"Ares-Pena","sequence":"additional","affiliation":[{"name":"CRETUS Centre, Department of Applied Physics, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,28]]},"reference":[{"key":"ref_1","first-page":"108","article-title":"Footprint patterns obtained by planar arrays","volume":"137","author":"Elliott","year":"1990","journal-title":"IEE Proc.
