“…In this context, 5G WCNs use an extended frequency spectrum to cover medium and high frequencies integrating mmWave technology [32,33]. Within this framework, a simple, low-profile, compact, dualpolarization, low-cost and suspended patch antenna has been designed to operate in a 3.3-3.8 GHz band used for a 5G base station with a gain of 8.95 ± 0.25 dBi [34]. In [29,35], a Sub-6 GHz dual-band 8 × 8 MIMO antenna and Sub-6 GHz 5G NR broadband eightantenna array have been designed, respectively, for 5G smartphones.…”

“…The technical justification for this choice lies in the fact that the main gains, in terms of the performance and efficiency of 5G, are based on the portions of the spectrum that are around WiFi [34]. Therefore, service providers can take advantage of frequencies below 6 GHz as a new exploitable spectrum, ensuring wider channels and better latency [29][30][31][32][33][34][35]. However, the major problem of this frequency band is that a large part of its spectrum is in free use and that the interference problem caused by the multitude of users must be solved.…”

The evolution of the global wireless market is accompanied by an increased need in terms of speed and number of users, lower latency, better coverage, better spectral efficiency and quality of service, etc. To meet these needs, 5G has recently been introduced as an effective solution which targets, via the large scale deployment of symmetric antennas, a wide variety of sectors such as energy, health, media, industry, transport and especially wireless cellular networks which are among the most important pillars of modern societies. Multiple Input, Multiple Output (MIMO) systems, which have been extended to “Massive MIMO” mode and which consist of increasing the number of radiating elements involved in the transmission and reception of the radio link, are a very promising solution for improving the spectral efficiency of wireless communication systems (WCSs). Motivated by the aforementioned developments, the present paper investigates the increased capacity of MIMO systems to improve transmission in WCSs using 5G. It carefully focuses on the evaluation of the development level and technical contribution of MIMO systems and millimeter wave (mmWave) bands in 5G wireless cellular networks (WCNs) and gives important recommendations.

“…In the past few decades, researchers have been studying to improve the radiative performance of communication antennas. The microstrip patch antenna is disused in [1], [2]. Therefore, the development of wireless networks is crucial because 5G technology uses high-frequency bands and wide signal bandwidth to increase the transmission bit rate, thus providing better coverage with less power consumption [3], [4].…”

This paper is presents a microstrap patch with a T-shaped rectangular antenna workings; the T-shaped patch operating at 3.6 GHz resonating frequency range for 5G application (from 2.9 to 4.4 GHz) repectively. The overall size of the proposed antenna is 22×24×0.25 mm3; the feeding technique using a 50 Ω feed line to the antenna. The proposed antenna is printed on compact Rogers RT 588 lz substrate having permittivity (ɛr) 2.00, loss tangent (tan δ) 0.0021, with thikness 0.2 mm. The proposed antenna introducesmany advantages like small size, low profile, and simpler structure. The characteristics such as radiation pattern, reflection coefficient, gain, current distribution, and radiation efficiency are respectively presented and discussed, using CST microwave study in simulating and analysing. Introducing a slot with a rectangular T-shaped patch antenna achieved lower frequency with 98.474% radiation efficiency and peak gain of the proposed antenna at 2.52 dB. The fractional bandwidth is 42.81% (2.90 GHz to 4.48 GHz) with a resonant frequency of 3.6 GHz and return loss at 28.76 dB. This frequency band attributessuited 5 G mobile application.

“…The number of feed probes of the differentially fed antenna is twice that of the single‐ended antenna, which greatly increases the difficulty and cost of feed network design. In addition, the patch antenna using the single‐ended feed scheme cannot maintain a stable or symmetrical radiation pattern 12 . Therefore, under the premise of a simple feed network, it is particularly important to design a single‐ended differentially fed patch antenna.…”

A compact differentially fed dual‐polarized patch antenna with filtering performance is proposed for 5G applications. By utilizing the half‐wavelength standing current along the open‐ended microstrip line, the out‐of‐phase output signals are obtained. Utilizing the E‐shaped coupled resonator in series with the open‐ended microstrip line, balanced differential feeding with filtering property are realized, as excitation for the patch. The filtering patch antenna was fabricated for demonstration. Measured results show that the antenna has −15 dB impedance bandwidths of 13.7% (3.26–3.74 GHz) and 14.2% (3.25–3.75 GHz) for two polarizations, respectively, covering the 5G band (3.3–3.6 GHz). The patch antenna achieves good port isolation and cross‐polarization discrimination. In addition, the measured gain is higher than 6.8 dBi within operating band. Out of the operating band, the gain drops sharply, exhibiting a bandpass response. The out‐of‐band radiation suppression level of the proposed filtering patch antenna is larger than 16 dB.
