This initial solution is devoted to generating an equivalent pure real shaped-beam pattern for a concrete synthesis scenario. However, these new solutions are not based on real symmetric distributions; hence, not based on the generation of pure real patterns. The bandwidth performances and tolerance to errors provided by the multiple solutions in the array design are analyzed by considering different architectures, also including mutual coupling models and element factor expressions due to accuracy purposes. In addition, a technique to obtain efficient linear arrays by designing resonant structures is addressed. Examples involving both standard linear arrays of half-wavelength cylindrical dipoles and resonant linear arrays generating flat-top beam patterns are reported and discussed. Additionally, an extension to planar arrays performed by means of a generalisation of the Baklanov transformation through collapsed distribution techniques inspired in the well-known method devised by Tseng and Cheng is performed. In such a way, an analysis of the quality of solutions for generating circular and elliptical footprints with controlled both SLL and ripple which are highly interesting in the framework of space vehicle applications.<\/jats:p>","DOI":"10.3390\/s21010062","type":"journal-article","created":{"date-parts":[[2020,12,24]],"date-time":"2020-12-24T09:02:44Z","timestamp":1608800564000},"page":"62","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Multiple Solutions Starting from Real Shaped Beams in Equispaced Linear Arrays"],"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 Institute, Department of Applied Physics, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camilo","family":"L\u00f3pez-Castro","sequence":"additional","affiliation":[{"name":"CRETUS Institute, Department of Applied Physics, University of Santiago de Compostela, 15782 Santiago de Compostela, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4522-6903","authenticated-orcid":false,"given":"Paolo","family":"Rocca","sequence":"additional","affiliation":[{"name":"ELEDIA@UniTN, Department of Information Engineering and Computer Science (DISI), University of Trento, 38122 Trento, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8561-093X","authenticated-orcid":false,"given":"Juan Antonio","family":"Rodr\u00edguez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"CRETUS Institute, 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 Institute, 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 Institute, 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":[[2020,12,24]]},"reference":[{"key":"ref_1","first-page":"1554","article-title":"A method of calculating the field over a plane aperture required to produce a given polar diagram","volume":"93","author":"Woodward","year":"1947","journal-title":"J.
