“…where f H is the superior frequency of the emission point and f L is the inferior frequency of the emission point (-10 dB). The central transmission frequency is given by the average of the -10 dB points [8]. Firstly, it was used the transmission line model equations, which are the basis of the microstrip antenna theory, in order to design a rectangular antenna (due to the simplicity of assembling) which resonates in the central frequency of the 5G technology (26 GHz).…”

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.

“…In [10], SRR is embedded in the defected ground structure, which exhibits unique transmission characteristics. In [11], SRR is modified to a slot-type structure for rejecting unwanted frequency band in an ultra-wideband antenna. In this article, the slot-type SRR is used as a perturbation element to excite the space-orthogonal degenerate mode of a square patch resonator.…”

A slot‐type split‐ring resonator (SRR) as a new type of perturbation element for dual‐mode square patch resonator is introduced in this article.The slot‐type SRR used in the patch resonator allows coupling between the two degenerate modes. Moreover, coupling characteristics can be adjusted by the location of slot‐type SRR. By adding two notches in the dual‐mode filter with slot‐type SRR, the high degenerate mode near the passband is eliminated, and the center frequency is lowered slightly. It has been verified by both simulation and measurement. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 2011; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.26148

A simple and compact U‐shaped antenna with an ultrawideband characteristic is presented. The proposed antenna consists of a modified radiation patch fed by a microstrip line and a slot on the ground plane. In order to improve impedance matching at a lower band, the narrow strip is inserted at the center of the patch, and the ground plane is optimized with the inverted T‐shaped slot. Its performance is demonstrated from S‐parameters and radiation patterns. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2265–2269, 2014
