“…The proposed antenna was compared with previous research such as [28]: a circular monopole antenna on an FR4 substrate that covered the UWB (3.1-5.3 GHz) and was obtained at distances of −200 m; [29]: a helical antenna mounted on drones of high frequency (HF) band supporting 9.0-9.3 MHz; [30]: a bow-tie monopole antenna structure on a Rogers substrate adjusted with three structures (CPBA, WBA, and WRLBA) covering the frequency of 2-10 GHz, 4-10 GHz, and 0.8-10 GHz, respectively; [31]: a dual-band monopole antenna on an FR4 substrate fabricated for 2.45 GHz and 5.80 GHz; and [32]: a Maxim antenna structure designed for operating in ISM bands at 902-928 MHz. This comparison focused on antenna efficiency obtained from the frequency range, dimensions of the antenna, and the antenna gain.…”

“…A dual-band monopole antenna structure with two port connectors was used to reduce the complexity of an antenna structure built on FR4 with dimensions of 900 × 600 mm 2 , a thickness of 1.6 mm, and a dielectric constant of 4.4. The antenna structure with a basic rectangular shape showed a low frequency of 2.45 GHz at a bandwidth of 171 MHz and a high frequency of 5.80 GHz at a bandwidth of 643.6 MHz [31]. A Maxim antenna structure was used to verify drones which were not allowed to approach an airport operating in unlicensed ISM bands at 902-928 MHz.…”

This paper presents the study of an H-and dual C-shaped planar dipole antenna by adding and etching technique for the triple-band of drone operating frequencies. Tuning the frequency range was performed to cover the VOR standard of [108][109][110][111][112][113][114][115][116][117][118] MHz, and the DME standard of 962-1,231 MHz. The antenna structure was fabricated on a PCB of FR4 with a dielectric constant (ε r ) of 4.4 and thickness (h) of 1.6 mm (material with low cost, compact size, and easy to use). The reflection coefficient (S 11 ) results of the simulation and measurement were in good agreement, which demonstrated the bandwidth frequencies of resonance frequency at 112 MHz (106-118 MHz), 331.50 MHz (323-401 MHz), and 1,087.50 MHz (920-1,301 MHz). The antenna gains were 1.73, 3.43, and 6.31 dBi, respectively, and the antenna radiation pattern was omnidirectional when it was used with H-plane. It was found in experiment that the proposed antenna could be installed in a drone with sending and receiving signals fittingly as desired. Furthermore, the proposed antenna is lightweight at just 0.4 kg, less than the original drone antenna (1.8 kg), and it does not require changing the antenna in each frequency range.

“…2 achieves the optimal trade-off between implantation ease and efficiency in developing a high-performance antenna. Based on the theory of microstrip antenna design [24] and previous research [25][26][27][28][29][30][31], the rectangular-shape monopole antenna model is used in this situation due to its simplicity of fabrication using standard tools and graphene sheets. The following is an empirical equation for any dimension in Fig.…”

Globalization has opened practically every country in the globe to tourism and commerce today. In every region, the volume of vehicles traveling through border crossings has increased significantly. Smartcards and radio frequency identification (RFID) have been proposed as a new method of identifying and authenticating passengers, products, and vehicles. However, the usage of smartcards and RFID tag cards for vehicular border crossings continues to suffer security and flexibility challenges. Providing a vehicle's driver a smartcard or RFID tag card may result in theft, loss, counterfeit, imitation, or vehicle transmutation. RFID sticker tags would replace RFID tags as vehicle border passes to solve the mentioned problem. The RFID sticker tag adheres to the windscreen, side screen, dash, hood, or door of the vehicle, or any other acceptable location. Any damage or stripping from the installed location may cause data corruption and cannot be reused. Overall, these sticker tags will make the border crossings more secure and efficient. This article focuses on designing a rectangular-shaped RFID sticker tag antenna made of graphene sheets as a possible solution for smart border crossings. The proposed antenna is mathematically designed and analyzed with CST software to determine the optimum parameters. The design parameters are then used to create an antenna on a prepared graphene sheet. The performance results are carried out with CST software and a network analyzer. The designed RFID antenna stick on a car windscreen offers approximately 900 MHz bandwidth over the frequency range from 1.8 GHz to 2.7 GHz with an average gain of 1.23 dBi at the frequency to be used of 2.4 GHz microwave RFID band. The radiation is an omnidirectional pattern. The proposed graphene-sheet rectangular-shape monopole antenna is compact, low-cost, and bendable to fit into the windscreen of a car while retaining excellent wave propagation capabilities. These findings illustrate the suggested antenna's potential as an RFID tag antenna in a vehicular smart border pass system.

“…In [4], the design of compact CPW-FED dual band notched UWB square ring antenna with a bandwidth was depicted. In addition, an antenna bandwidth could be improved by using slots or adding parasitic patch around a central element [5][6][7]. The 3rd generation partnership project (3GPP) has allocated the spectrum for 5G in two ranges.…”

With the recent development of wireless communication systems and the 5G spectrum, mobile broadband technology (MBB) has been thriving. In this contribution, the design of an Ultra Wide Band T-slotted rectangular microstrip patch antenna is presented which is suitable for high data rate applications. The antenna is fed using a coplanar waveguide and is designed for two central operating frequencies, the lower resonant frequency at 3.6 GHz, an internationally recognized standard for 5G wireless mobile communications and a higher frequency at 6.8 GHz, which is part of the new wifi-6E standards. All data of the characteristic parameters have been obtained by using the Computer Simulation Technology Microwave Studio Student suite 2021 (CST MWS).
