Development of Supershaped Antennas for 5G Applications
| Resumo: | The 5G network will revolutionize telecommunications, when it comes to smart wear able devices and wireless devices. On smart wearables, for applications close to the body, the antennas are usually built with rigid materials, reducing the users comfort. However, the development of textile antennas has the ability to promote the full inte gration of electronic systems in clothing, improving the users comfort. The shape of the radiating element is also important, as it eases the integration and concealment of the antenna in patterns. The superformula allows to describe a wide variety of geo metric, abstract and natural shapes, being suitable for the design of a radiant element inspired by nature. According to the literature, the superformula has been used in the design of various types of rigid antennas, improving their performance through greater flexibility in shape modeling. In this dissertation, a parametric analysis of the superformula was performed in patch antennas and printed monopoles. On patch antennas, the superformula allowed the development of a rigid printed antenna for 3.5 GHz with performance similar to a circular patch antenna, and with a smaller radiating area, promoting comfort and dis cretion. A version of the same antenna with increased bandwidth was also simulated and a textile printed antenna was proposed for 3.5 GHz. Based on this, a shirt was cre ated where the substrate was the shirts material itself. Then, the antenna performances were compared before and after the integration in the clothing, as well as the perfor mance close to the body. On printed monopoles, the impact of the superformula on its performance was greater than in patch antennas. This analysis led to the simulation and fabrication of a rigid printed monopole and a textile one, both for 5G applications. |
