The pervasiveness of mobile internet, in conjunction to the ubiquitous computing of the internet-of-things has claimed the concept of 5G technology research to allow massive growth of machine communications. One of the main challenges is the scalability problem, which implies issues like small mobile device antennas to fit in the limited amount of space for the smartphone’s design, followed by radiation control and low cost. The purpose of this paper is to develop an antenna, which meets the next generation of the mobile technology 5G as well as other resources available and desired in a smartphone (GPS – 1575 MHz, WLAN – 2.4 GHz, 3G – 2.1 GHz, Brazilian 4G – 2.6 GHz e GSM – 900 – 1800 – 1900 – 2100 MHz). The design adopted only one ultra-wideband microstrip antenna that resonates in the frequencies of these technologies. This kind of antenna is thin, has low cost and good radiation control. Besides, this is the most popular type of antenna in mobile devices; the radiant elements use the manufacturing process of printed circuits. It is built in a plate composed by a conductor (the radiant element of the antenna), a substrate, and by another conductor, which is the ground plate. The principal feature of an ultra-wideband antenna is the usage of 1.5 GHz bandwidth or more. The prototype was manufactured and the simulation results for each type of technology resources are compared.

The searching for multifunction devices, such as smartphones, is growing in the mobile devices market. These gadgets have several mobile current technologies, for instance: WiFi, high performance mobile internet (3G and 4G), GPS (Global Positioning System), GSM (Global System Mobile) ou (Global System for Mobile communication)and Bluetooth®. In a globalized world it is a trend that the velocity of the internet maintain increasing over the years in order to, among other functions, perform real-time video calls using, for example, a connection provided by a mobile operator. In addition, the screens of these devices are also increasing in size for a better user experience in video calls with high resolution. However, although the screens are increasing, the consumers are also looking for thinner devices. Therefore, in order to reduce the dimensions of a smartphone it is necessary to shrink its internal components. So, some techniques are employed, such as the manufacture of integrated circuits, which considerably decreases the circuit size. Supplementary, is necessary to use printed antennas, which has an extremely small thickness. The necessity of a mobile internet with higher speeds has promoted the research and the constant development of new technologies such as 4G that can reach data rates of 100 Mbps. Despite the fact that this technology was not totally implanted in several places, there is a slightly growing on research and development of the Fifth generation, i.e, 5G of mobile telecommunications, which is capable to operate with extremely high data rates transfer and using the frequency bands of electromagnetic spectrum above 25 GHz [1-3]. In addition, the prospect of growth in the number of devices connected simultaneously after the implementation of the Internet of Things (IoT) has concerned mobile technology companies, who has seek a solution to meet future demand efficiently, highligthing the importance of [...]
