“…The current 4G system has been saturated because of limited bandwidth [2]. It is essential to improve the performance of the mobile network in terms of capacity to fulfill the future requirements of high-speed mobile networks [3][4][5][6][7]. Fifth generation (5G) is preferred over 4G owing to the availability of wide bandwidth which enhances network performance.…”

In this paper, antipodal Vivaldi antenna is designed for 5th generation (5G) mobile communication and Ku-band applications. The proposed designed has three layers. The upper layer consists of eight-element array of split-shaped leaf structures, which is fed by a 1-to-8 power divider network. Middle layer is a substrate made of Rogers 5880. The bottom layer consists of truncated ground and shorter mirror-image split leaf structures. The overall size of the designed antenna is confined significantly to 33.31 × 54.96 × 0.787 (volume in mm3), which is equivalent to 2λo× 3.3λo× 0.05λo (λo is free-space wavelength at 18 GHz). Proposed eight elements antenna is multi-band in nature covering Ku-bands (14.44–20.98 GHz), two millimeter wave (mmW) bands i.e., 24.34–29 GHz and 33–40 GHz, which are candidate frequency bands for 5G communications. The Ku-Band is suitable for radar applications. Proposed eight elements antenna is very efficient and has stable gain for 5G mobile communication and Ku-band applications. The simulation results are experimentally validated by testing the fabricated prototypes of the proposed design.

This study presents an origami inspired sub-6 GHz accordion monopole antenna for 5G applications. Parametric study is performed by varying monopole height, fold width and bevel angle to examine the antenna performance in the 1 GHz -6 GHz frequency range. The proposed antenna is designed with the values that yield the best performance in accordance with the results of parametric study. Antenna behavior is then evaluated in terms of Return Loss, gain and radiation pattern. The proposed antenna operates in 1.22 GHz -6 GHz frequency range which covers almost the entire sub-6 GHz range with an approximate impedance bandwidth of 132%. Hence, the designed antenna structure has a good performance in the sub-6 GHz and it is a promising design for 5G applications.

“…A 24 GHz MIMO multilayer Yagi antenna has been manufactured for 5G applications in IoT scenarios, which has 10.9 dBi gain and 6.9 GHz bandwidth. The planar structure equivalent had 8.9 dBi gain and 4.42 GHz bandwidth [ 24 ]. However, its large size is a drawback, which leads to high manufacturing costs [ 25 ].…”

Upcoming 5th-generation (5G) systems incorporate physical objects (referred to as things), which sense the presence of components such as gears, gadgets, and sensors. They may transmit many kinds of states in the smart city context, such as new deals at malls, safe distances on roads, patient heart rhythms (especially in hospitals), and logistic control at aerodromes and seaports around the world. These serve to form the so-called future internet of things (IoT). From this futuristic perspective, everything should have its own identity. In this context, radio frequency identification (RFID) plays a specific role, which provides wireless communications in a secure manner. Passive RFID tags carry out work using the energy harvested among massive systems. RFID has been habitually realized as a prerequisite for IoT, the combination of which is called IoT RFID (I-RFID). For the current scenario, such tags should be productive, low-profile, compact, easily mountable, and have eco-friendly features. The presently available tags are not cost-effective and have not been proven as green tags for environmentally friendly IoT in 5G systems nor are they suitable for long-range communications in 5G systems. The proposed I-RFID tag uses the meandering angle technique (MAT) to construct a design that satisfies the features of a lower-cost printed antenna over the worldwide UHF RFID band standard (860–960 MHz). In our research, tag MAT antennas are fabricated on paper-based Korsnäs by screen- and flexo-printing, which have lowest simulated effective outcomes with dielectric variation due to humidity and have a plausible read range (RR) for European (EU; 866–868 MHz) and North American (NA; 902–928 MHz) UHF band standards. The I-RFID tag size is reduced by 36% to 38% w.r.t. a previously published case, the tag gain has been improved by 23.6% to 33.12%, and its read range has been enhanced by 50.9% and 59.6% for EU and NA UHF bands, respectively. It provides impressive performance on some platforms (e.g., plastic, paper, and glass), thereby providing a new state-of-the-art I-RFID tag with better qualities in 5G systems.
