“…From Table 2, we note that the antenna radiation efficiency is higher than the designs reported in [10-13, 19, 22], the bandwidth is wider as compared to the antennas cited in [19,20,22]. In terms of beam gain, the rectangular MSPA in this paper outperforms the designs reported in [14,20,22]. Generally, the proposed single element rectangular MSPA gives an exceedingly competitive performance as compared to similar structure antennas reported in the scientific literature.…”

“…Therefore, to overcome the drawbacks of MSPA mentioned above and enhance its performance for 5G communications, several designs of single element MSPA have been reported in the literature. These include modifying of feeding technique [9], using defected ground structure (DGS), and a slotted patch [10][11][12], using various substrate material types [13], changing the patch shapes [14][15][16], and using artificial material like metamaterial [17].…”

“…However, the antenna bandwidth is narrow, which is against federal communications commission (FCC) proposal, and the magnitude of voltage standing wave ratio (VSWR) is large for wireless communications. Lastly, attempting to improve the performance, MSPA designs are given in [11,12,14], and wide bandwidth, good gain, and low return loss values are obtained. Besides, the overall size of a single patch is not good, which in turn creates incompatibility issues for the small handheld mobile devices.…”

In this paper, a 28 GHz broadband microstrip patch antenna (MSPA) for 5G wireless applications is presented. The Rogers RT/Duroid5880 substrate material, with a dielectric constant of 2.2, the thickness of 0.3451 mm, and loss tangent of 0.0009, is used for the studied antenna to operate at 28 GHz center frequency. The proposed design of antenna is simulated by using CST studio suite. The simulation results highlight that the studied antenna has a return loss of -54.49 dB, a bandwidth of 1.062 GHz, a gain of 7.554 dBi. Besides, radiation efficiency and the sidelobe level of the proposed MSPA are 98% and 18.4 dB, respectively. As compared to previous MSPA designs reported in the recent scientific literature, the proposed rectangular MSPA has achieved significantly improved performance in terms of the bandwidth, beam-gain, return loss, sidelobe level, and radiation efficiency. Hence, it is a potential contender antenna type for emerging 5G wireless communication applications.

“…These applications require in RF band (from a few hundred MHz to a few GHz) low consumption, such as for IoT. In millimeter bands (between 30 GHz and 300 GHz), we will target either broadband (in particular for 5G around 28 GHz [3] and 38 GHz [4], and future generations beyond 100 GHz [5] for which the rate can reach 10 Gbps), or resolution (for medical imaging between 100 and 200 GHz), [6,7]. Today, RF applications are used in different scientific fields.…”

The 3 dB, 90° coupler is a passive device with four ports that allows each output to collect half the input power but in phase quadrature. The 3 dB coupler is often made in microstrip technology where different quarter-wave sections are present to ensure impedance matching. In order to be able to design a duplexer operating on several frequency bands, a tunable hybrid coupler was designed in this work. The coupler must be adjustable to operate on the bands 3.3-3.6 GHz and 4.8-5 GHz. The proposed coupler will cover the bandwidth requirements of 5 bands (3.3-3.6 GHz) and (4.8-5 GHz) to be deployed in China. The hybrid coupler will be designed by two methods. At the first stage, the coupler will be designed by lumped elements, and then it will be designed using transmission lines. Via the ADS tool, the 3 dB 90° coupler is dimensioned and simulated to work well at the center frequency of 3.45 and 4.9 GHz. These two frequencies are belonging to the 5G bands. The main purpose of this work is to simulate and analyze the proposed coupler for 5G frequency bands. The simulation of the reflection coefficient, i.e., S11 parameters in amplitude and phase are presented and discussed. From simulation results we observed that the proposed coupler works under the requirement of 5G application.

The objective of this article is to study the performance of the RFID (Radio Frequency Identification) technology and especially the passive UHF RFID (Ultra High Frequency RFID) tags by mean of simulation. In this paper, three patch antennas with different matching techniques for passive UHF-RFID tags are proposed. T-Match, inductively coupled loop and nested-slots layouts are adopted in order to achieve complex impedance matching between the antennas impedance and the chip selected at 915 MHz with high performance. The antennas are printed on a Rogers RT/duroid 5880 substrate with a relative permittivity of 2.2 and thickness of 1.575 mm. Studies demonstrate that the inductively coupled loop and the nested-slots matching techniques are the good candidates to adapt the antenna impedance to chip impedance, while adaptation in T is intended to be only used for dipole antennas. We have achieved an adaptation of 99.90 %, a very wide bandwidth of 409.6 MHz, a broadside an asymmetrical radiation pattern in the E-plane, a read range of 21.19 m and an antenna gain of 4.17 dB with the inductively coupled loop matching technique, while with the nested-slots matching method, we have acquired an adaptation of 99.94 %, a directive antenna, a read range of 19.83 m and a gain of 3.59 dB.
