Lo sviluppo tecnologico misura la crescita economica di una nazione e in questi anni abbiamo assistito ad una rapida crescita dei dispositivi wireless, grazie al contributo di esperti del modo scientifico, accademico ed industriale. La necessità di tale sviluppo è scandito dal contesto in cui sempre più persone e oggetti sono connessi, in ogni momento in ogni luogo e con chiunque, quindi diventa fondamentale capire come gestire questa complessità e cogliere le opportunità per generare nuovi modelli di business per l'industria tecnologica. Le sfide del mondo d'oggi ci spingono nel trovare innovative soluzioni nel mondo delle telecomunicazioni, posto in cui questi dispositivi trovano impiego, ma per necessità ci si è voluti spingere ben oltre, impiegandoli nel settore dell'Internet of Things (IoT) o biomedicale giusto per citarne alcuni. Il largo uso di sistemi wireless, ha spinto, ormai da molti anni la ricerca in ambito accademico ma anche industriale a produrre design di antenne a microstriscia che rispecchiassero alcune fondamentali caratteristiche: che siano a basso costo di produzione, a banda larga, alto guadagno e che la loro struttura fosse leggera e scalabile. Parte della mia ricerca riguarda l'investigazione di innovativi design di antenne Ultra Wide Band (UWB), l'intuizione per superare le limitazioni dei comuni design è stata quella di utilizzare una superformula introdotta dal biologo Johan Gielis il cui obiettivo è selezionare le migliori in termini di prestazioni elettromagnetiche, seguendo le caratteristiche elencate precedentemente. Ogni forma geometrica è descritta da una equazione matematica, l'utilizzo della superformula ci semplica drasticamente il problema matematico, facendo variare i pochi parametri presenti nella superformula si riesce a generare un infinità di forme presenti in natura e anche forme di tipo di astratte. Per completare lo studio elettromagnetico e parametrico, sono stati utilizzati i software CST Studio Suite e Matlab, realizzando un'interfaccia tra i due software per semplificare lo studio parametrico delle antenne.

Abstract
The rate of technological development measures the economic growth of nation's and in last year’s we have witnessed to a rapid development of wireless devices thanks to the contributions of science research and experts of industry. The need of this development is marked by the context in which more people and objects are connected every time and everywhere with anyone and there- fore it becomes fundamental to understand how to handle this complexity and take the opportunities to generate new models of business for the technology factory. The challenges of world are pushing us to find innovative solutions in the telecommunications world, but having to push us further, finding significant use in the IoT or in the biomedical engineering, just to name a few. The widespread use of wireless systems has pushed for many years academic and industrial research to produce microstrip antennas design that submit some of the key features: low-cost of production, broadband, high gain and that their structure was light and scalable. Engineers motivated by that these antennas are integrable with microwave circuits have made them even more popular. Part of my research concerns the investigation of innovative Ultra-Wide Band (UWB) antennas design, the intuition was to use the supershaped introduced by the biologist Johan Gielis with the goal of selecting the best antennas in terms of electromagnetic performance, and then obtaining a comparison of equivalent circuits from them. Varying the few parameters present in the supershaped, it is possible to generate an infinity of forms in nature but also of an abstract nature, considering that each form is described by a mathematical equation, the use of supershaped extraordinarily simple the mathematical problem. In order to complete the electromagnetic and parametric study, CST Studio Suite and Matlab software has been used, realizing an interface between the two to simplify the parametric study of antennas.I documenti in UNITESI sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
