“…This sub-section describes the 5G single elements, arrays, and MIMO antennas operating at lower 5G frequencies. Some of the literary works have reported a single element antenna for 5G applications [40][41][42][43][44][45][46]. The 5G antenna reported in [39] is a magneto-electric dipole antenna with tapered H-shaped ground, operating at a sub-6 GHz band.…”

“…As a single-element antenna cannot obtain high gain, therefore, multi-element array configuration is one of the principal methodologies to deal with this issue. In an array, multiple antenna radiations are added constructively to enhance the gain of the antenna, thus, administering the path loss to some extent [46]. Recently, various antenna array designs have been reported for 5G sub-6 GHz systems [47][48][49][50].…”

An antenna is of substantial importance for a communication system as the design of an air interface is mainly reliant on the antenna design. With the significant wireless evolution from 1G to 6G, technologies and network capacities are also evolving to fulfill the promptly growing customer demands. These continually increasing demands have gone concurrently with extensive technological accomplishments of the antenna design community. This chapter discusses the sub-6 GHz and millimeter-wave (mm-wave) fifth-generation (5G) antennas, including antenna arrays, multiple-input, multiple-output (MIMO) technology, beam-steering techniques, metasurfaces, and other techniques to achieve the current and impending fast connectivity. Moreover, the design specifications, research directions, various technologies expected to be involved, and challenges in the design, fabrication, and measurement of the sixth-generation (6G) antennas at the THz band have also been presented. In addition, antenna-in-package (AiP) and antenna-on-chip (AoC) technologies with proper technology solutions have also been discussed.

Nusindo Rekatama Semesta is a company located in the Sleman Regency area, Jombor Lor, Sinduadi. PT. Nusindo Semesta is a company in the corporate management industry that has been operating since February 2011. PT. Nusindo Rekatama Semesta provides wireless hotspot facilities where employees and visitors who come can take advantage of an internet connection that can be accessed via laptops, smartphones, or other devices such as those that support wireless technology. However, the implementation of hotspots needs to be corrected; for example, per-client bandwidth still needs to be focused. It aims to overcome per-client bandwidth usage and create a captive login portal as a security system so that those who do not have access rights cannot use internet access in the company. Using the hotspot login authentication system within the company. With the application of Mikrotik Router OS as a router in the company's network, it can overcome the instability of wireless network connections, and the captive portal login feature on Mikrotik can prevent users who do not have access rights from being able to use the internet access in the company.

This article proposes a compact dual-band circular-shaped implantable antenna for scalp and skin implantation applications. The proposed antenna covers the 1.395-1.432 GHz Wireless Medical Telemetry Service (WMTS) band and 2.4-2.48 GHz Industrial, Scientific, and Medical (ISM) band with a compact volume of 0.0000017λ 3 0 . The antenna maintains a realized peak gain of −24.5 dB and −20.6 dB, respectively, at 1.43 GHz and 2.44 GHz. Moreover, the gain pattern of the antenna is in the off-body direction which is a desirable feature for implantable scenario. It also depicts stable responses under different implantation scenarios. Moreover, the via free configuration is an advantageous feature of the proposed antenna in the context of fabrication complexity. Furthermore, a holistic design approach is considered with integrated components for device-level architecture. The resonance behavior of the proposed antenna structure is also analyzed by developing a conceptual equivalent circuit model. The evaluated specific absorption rate (SAR) complies with the regulated human safety standard. The biotelemetry link capability is also evaluated through the link margin (LM) calculation of the proposed antenna and is able to establish a communication link at a range of 4.5 m distance. INTRODUCTIONThe advancement in technology has considerably influenced humans' day-to-day life. In recent times, the development of biomedical devices for human health monitoring has received considerable attention [1][2][3][4][5][6]. These biomedical devices have been broadly categorized into two different categories: (1) wearable and (2) implantable/ingestible devices where the antenna has a pivotal role to play [2,3]. Apart from wearable medical devices, researchers have taken a keen interest in the design and development of implantable medical devices (IMDs). In this regard, it is essential to note that IMDs have been developed for sensing, monitoring, stimulation, and drug delivery to improve the quality of human life [3,4]. These devices assist in patients' diagnostic and therapeutic purposes [3]. The wireless IMDs with biotelemetry functionalities are beneficial with the integration of modern communication technology [3][4][5]. The wireless IMDs comprise different components, including battery, electronic circuitry, sensor, and implantable antenna.In this context, it is worth noting that an efficient implantable antenna plays a vital role in establishing reliable communication between the IMD and external control unit. It should be noted that, unlike the traditional antenna for free-space application, designing an implantable antenna involves many challenging factors such as miniaturization, operating frequencies, specific absorption rate (SAR) for human safety, and biocompatibility with human tissue [4][5][6]. In this context, antenna miniaturization with desired characteristics is one of the main challenges as the space available for antenna placement in the compact implantable device is limited. In the recent past, researchers have propose...
