“…A comparison of the proposed antenna and recently published leading-edge wideband printed monopole antennas is presented in Table 2. The proposed antenna outperforms the reported antennas in both electrical size and bandwidth, except the elliptical monopole reported in [7] and the antenna reported in [18]. Nevertheless, the antenna presented here demonstrates a better gain performance and has a simpler structure than those reported in [7,18].…”

A printed monopole antenna with enhanced bandwidth and reduced size using a bounding box structure is presented in this paper. The initial design comprises a microstrip‐fed rectangular monopole with a partial ground structure. A feed line offset, a slit etched on the feed line, an asymmetric transition connecting the feed line and the monopole, and an inverted T‐slot embedded in the ground are used to ensure good impedance matching. The design is modified by incorporating a bounding box structure, which introduces additional resonances hence an enhanced impedance fractional bandwidth reaching 156% (0.28 to 2.27 GHz) is obtained as compared to only 72% (0.75–1.60 GHz) realised for a conventional monopole. The electrical size of the proposed antenna is also reduced from 1.01λlthickmathspace×0.60λl to 0.39λl × 0.24λl (where λl denotes the wavelength corresponding to the lowest operating frequency of the antenna) using the bounding box configuration. The experimental and predicted results are in good agreement, and the proposed antenna demonstrates good radiation characteristics over the operating bandwidth. The proposed antenna can be applied in DVB (530–860 MHz), GSM850 (824–894 MHz), GSM900 (880–960 MHz) DCS (1710–1880 MHz), PCS (1850–1990 MHz), and UMTS (1920–2170 MHz) systems.

“…As shown in Fig.8, the experimental results of an electrically compact printed monopole antenna have been elaborated in [52] with the operational bandwidth of 185% (0.115-2.90 GHz) for -10 dB, peak gain and radiation efficiency of 2.35 dBi and 78.8%, occurred at 1.45 GHz. The antenna's layout is approximated to a back-to-back triangular formed patch structure that is stimulated by a common feed-line with a meander-line T-form divider.…”

In this review paper, a comprehensive study on the concept, theory, and applications of composite right/left-handed transmission lines (CRLH-TLs) by considering their use in antenna system designs have been provided. It is shown that CRLH-TLs with negative permittivity and negative permeability have unique properties that do not occur naturally. Therefore, they are referred to as artificial structures called "metamaterials". These artificial structures include series left-handed (LH) capacitances , shunt LH inductances , series right-handed (RH) inductances , and shunt RH capacitances that are realized by slots or interdigital capacitors, stubs or via-holes, unwanted current flowing on the surface, and gap distance between the surface and ground-plane, respectively. In the most cases, it is also shown that structures based on CRLH metamaterial-TLs are superior than their conventional alternatives, since they have smaller dimensions, lower-profile, wider bandwidth, better radiation patterns, higher gain and efficiency, which make them easier and more cost-effective to manufacture and mass produce. Hence, a broad range of metamaterial-based design possibilities are introduced to highlight the improvement of the performance parameters that are rare and not often discussed in available literature. Therefore, this survey provides a wide overview of key early-stage concepts of metematerial-based designs as a thorough reference for specialist antennas and microwave circuits designers. To analyze the critical features of metamaterial theory and concept, several examples are used. Comparisons on the basis of physical size, bandwidth, materials, gain, efficiency, and radiation patterns are made for all the examples that are based on CRLH metamaterial-TLs. As revealed in all the metematerial design examples, footprint area decrement is an important issue of study that have a strong impact for the enlargement of the next generation wireless communication systems.

“…Use of a monopole radiator with concentric split-ring resonators enable fractional bandwidth of the antenna enhancement from 41 to 87% [7]. There are other compact, miniature and microstrip multiband antennas for smooth switching between networks [8], [9] that lends easily in bracing the speed, latency, and above all cost-effectiveness based on composite right/left handed transmission line (CRLHTL) metamaterials. It enables long range access at low cost, thereby making it excellent application for distribution and logistics systems besides small footprint, global portability and excellent radiation characteristics [10], [11].…”

The proposed framework of Four Layer Robust Storage in Cloud (FLRSC) architecture involves host server, local host and edge devices in addition to Virtual Machine Monitoring (VMM). The goal is to protect the privacy of stored data at edge devices. The computational intelligence (CI) part of our algorithm distributes blocks of data to three different layers by partially encoded and forwarded for decoding to the next layer using hash and greed Solomon algorithms. VMM monitoring uses snapshot algorithm to detect intrusion. The proposed system is compared with Tiang Wang method to validate efficiency of data transfer with security. Hence, security is proven against the indexed efficiency. It is an important study to integrate communication between local host software and nearer edge devices through different channels by verifying snapshot using lamport mechanism to ensure integrity and security at software level thereby reducing the latency. It also provides thorough knowledge and understanding about data communication at software level with VMM. The performance evaluation and feasibility study of security in FLRSC against three-layered approach is proven over 2 32 blocks of data with 98% accuracy. Practical implications and contributions to the growing knowledge base are highlighted along with directions for further research.
