“…Nakmouche et al, have presented an enhanced gain FSS superstrate reflector surface-based monopole antenna using machine learning. The authors arranged a superstrate FSS layer above 6.0 mm distance from the main radiator which enhance the gain from 3.12dBi to 8.89dBi [16]. Belen has developed an FSS antenna that results in the enhancement of gain 7.15dBi for the industrial scientific and medical (ISM) radio band [17].…”

The development, analysis, fabrication, and measurements of an inset-feed frequency selective surface (FSS) monopole rectangular patch antenna based on the Fabry-Perot cavity (FPC) principle were discussed in this paper. The proposed antenna is fabricated on two pieces of flame retardant-4(FR4) substrate (FSS reflector) and RT Duroid 5880 substrate (main radiating patch) of equal size 49mm×49mm×1.6mm. The use of FR4 controls the cost of the antenna while the RT Durid maintains low losses and supports improvement in gain and radiation characteristics. The FPC principle is utilized to enhance antenna gain and directional radiation characteristics. The distance between the substrate and FSS layer is evaluated by developing a relationship using a machine learning artificial neural network (ANN) model-based method by speculating the output through iterations and it is validated by the high-frequency structure simulator (HFSS) optimization process. Equally spaced 15 dipole strips FSS layer is used as reflector surface which yields enhanced gain from 4.41dBi to 8.99dBi (∽4.58dBi improvement), unidirectional radiation patterns, and improved front-to-back-ratio (FBR) from 1.7dB to 17.5dB in the E-plane at the design frequency 5.5GHz. The antenna achieves a -10dB bandwidth from 1.12GHz to 8.64GHz (7.52GHz). The measured results are in close agreement with the simulated results. At the end, an electrical equivalent resistor, inductor, and capacitor (RLC) circuit of the proposed antenna has been generated from the antenna reflection coefficient. The reflection coefficient of the RLC equivalent circuit of the proposed antenna is validated using advanced design system (ADS) software. Since the antenna has ultra-wideband (UWB) performance, therefore it is most suitable for wireless 3G/4G/5G and Sub-6GHz lower frequency range (FR1), satellite, and RADAR communications.

“…Microstrip patch antennas are a very popular type of antenna due to their light weight, small size, and low manufacturing cost. ML techniques were used in [59] for the determination of the optimal location of the frequency selective (FS) reflector and the ground dimension of the monopole in composite antennas structure for 5G purposes. They said that the proposed technique can save up to 99% of the computational time compared with the conventional approaches.…”

<div align="center"><span lang="EN-US">A typical healthcare system needs further participation with patient monitoring, vital signs sensors and other medical devices. Healthcare moved from a traditional central hospital to scattered patients. Healthcare systems receive help from emerging technology innovations such as fifth generation (5G) communication infrastructure: internet of things (IoT), machine learning (ML), and artificial intelligence (AI). Healthcare providers benefit from IoT capabilities to comfort patients by using smart appliances that improve the healthcare level they receive. These IoT smart healthcare gadgets produce massive data volume. It is crucial to use very high-speed communication networks such as 5G wireless technology with the increased communication bandwidth, data transmission efficiency and reduced communication delay and latency, thus leading to strengthen the precise requirements of healthcare big data utilities. The adaptation of 5G in smart healthcare networks allows increasing number of IoT devices that supplies an augmentation in network performance. This paper reviewed distinctive aspects of internet of medical things (IoMT) and 5G architectures with their future and present sides, which can lead to improve healthcare of patients in the near future.</span></div>

In this paper, a high gain antenna using Frequency Selective Surface (FSS) is proposed. The compact structure is designed from a circular Ultra-wideband (UWB) monopole. Higher order modes of UWB antenna are suppressed by decreasing the thickness of the monopole, ground plane dimensions, and increasing the gap between the ground plane and the monopole. Symmetrical portion of circular monopole is etched to form a semicircular monopole, and an off-set feed is employed. Dual band characteristics and miniaturization are achieved by etching horizontal and vertical slots and reducing ground plane dimensions. An FSS reflector is designed for gain enhancement. This miniaturized antenna offers less blockage and therefore, higher gain improvement when an FSS is used as a reflector.
