“…The proposed antenna has a size reduction of 90% to other reported antennas like (Pant et al, 2021), (Hussain et al, 2018), (Hussain et al, 2017), (Lim et al, 2012), 84 and 88% of (Lim et al, 2012), (Lee and Jang, 2019) and 48, 56 and 77% of (Ahmad et al, 2021), (Yalavarthi, 2021), (Hassan et al, 2020) respectively. The proposed antenna has a peak gain of 2.8dBi, which is better than (Hussain et al, 2017), (Lim et al, 2012), (Lee and Jang, 2019), (Agrawal et al, 2021), however less than (Pant et al, 2021), (Hussain et al, 2018), (Chen et al, 2019), (Yalavarthi, 2021), (Hassan et al, 2020), (Ahmad et al, 2021). The MIMO antenna achieved minimum isolation of 15 dB and maximum isolation of 21 dB (D-ON) which is better than (Lim et al, 2012), (Yalavarthi, 2021), As a result, it can be concluded that the proposed MIMO antenna has favourable characteristics for use in 5G (sub-6GHz) and WLAN applications.…”

Purpose This study aims to present dual band reconfigurable MIMO antenna for 5G (sub-6 GHz) and WLAN applications. Design/methodology/approach To achieve optimum bandwidth, radiation pattern and radiation efficiency, the defected ground structure (DGS) and a rectangular stub connected with the DGS are used. To further cover the sub-6 GHz spectrum (3.4–3.6 GHz) for future 5G communications, a two-element multi-input multi-output (MIMO) antenna configuration is designed by using the single element antenna. The proposed reconfigurable MIMO antenna using a PIN diode is designed on an FR4 substrate with a dielectric constant of 4.4 and a loss tangent of 0.02 and a 35 × 20 × 1.6 mm3 dimension. Findings The proposed antenna achieved dual operating bands of 3.4–4.1 GHz (5 G sub-6GHz applications) and 4.99–5.16 GHz (WLAN application) in the D = ON state. For D = OFF state, the proposed antenna achieved 3.55–3.65 GHz and 3.66–4.05 GHz frequency bands for 5G (sub-6GHz) applications. In terms of the envelop correlation coefficient, diversity gain, mean effective gain, total active reflection coefficient and isolation between the ports, the proposed antenna’s diversity performance characteristics are investigated and the obtained values are 0.05, 9.9 dB, ±3dB, −4dB, −15dB, respectively. Research limitations/implications The fabricated prototype antenna on FR4 substrate has measurable parameters that are in good agreement with the simulated findings. Due to hardware design limitations, there is a minor difference between software and hardware results. Originality/value The proposed MIMO antenna is compact and reconfigurable for 5G (sub-6GHz) and WLAN applications, and from the graph, the measurements and simulations have been found to be in close agreement.

“…Interconnection systems are finding it increasingly difficult to meet these needs, while keeping deployment costs low. Despite its ability to meet expectations in terms of bandwidth and capacity, optical fibre is still fairly expensive and difficult to deploy, while the development of radio frequency systems is increasingly limited by the scarcity of frequencies [1]. To overcome these limitations whilst improving the quality of service offered by the latest generation of mobile network technologies, such as 5G, research is increasingly focusing on ways of combining the performance of optical fiber with the mobility of radio frequency (RF) systems in a single system [2].…”

Free Space Optical (FSO) communication systems are based on the use of infrared light to transmit information at high speed through the atmospheric channel. Their performance is therefore affected by the characteristics of the atmospheric channel. One of the most widely used methods of compensating for the effects of atmospheric factors is modulation.The main aim of this research is to demonstrate the improvement in FSO link performance using PolSK modulation in a subtropical environment such as Cˆote d’Ivoire. The performance indicators considered are bit error rate, channel capacity, outage probability and energy efficiency. The mathematical expression of the evolution of each of these indicators as a function of the atmospheric parameters of our environment was determined using the gamma-gamma model. A numerical evaluation of the results obtained was carried out using Matlab software. The results show that PolSK modulation offers the best results in terms of BER reduction, with a BER of the order of 10-11 for an SNR of 50dB, compared with BERs of 10-4 and 10-2 for BPSK and OOK modulations respectively. We obtain a probability of interruption of the order of 10-3 for PolSK modulation compared with 10-2 for BPSK modulation and 10-1 for OOK modulation. As for the channel capacity, we obtain the same value (4:1458bit/s) for PolSK and BPSK modulation compared with 3:8181bit/s for OOK modulation. BPSK modulation, on the other hand, stands out for its excellent energy efficiency.
