“…In references, 14–17 coplanar strip, simple strip, slot and half cutting CP antenna techniques, and inverted L‐ shaped PS with microstrip line had been developed for CP radiation. Semicircular patch antenna, 18 metal ridge septum with rectangle and triangle cascade, 19 trapezoidal monopole antenna, 20 two parasitic strips loaded CP antenna, 21 coplanar waveguide feeded T ‐shaped monopole antenna with inverted L ‐shaped grounded stub, 22 modified rectangular monopole, asymmetric ground plane, L ‐shaped strip with CPW feed, 23 and a DRA for circular polarization 24 were implemented for broadband, dual‐band, and dual‐sense applications. From the above literature survey, it is observed that the ARBW is improved with large antenna size.…”

SummaryA small size, dual‐band and dual‐sense monopole antenna is proposed to improve the axial ratio bandwidth (ARBW). The proposed antenna is considered on a low‐cost lossy FR4 substrate with parasitic strips (PSs) and partial ground plane of half guided wavelength dimensions. The dimension of the antenna in terms of wavelength is , where is the wavelength at the lowest resonant frequency. The circularly polarized (CP) mode is created for strong orthogonal electric fields and . The obtained phase difference (PD) between two electric fields and is varied from to under ARBW. The achieved ARBW is 3.68–3.8 GHz, 4.84–12.58 GHz, and impedance bandwidth (IBW) is 3.51–3.82 GHz and 4.28–15 GHz. The applications of the proposed antenna are International Telecommunication Union (ITU) for 5G, C‐band IEEE 802.11a wireless local area network (WLAN) at 5 GHz (5.15–5.825 GHz) and X‐band wireless systems.

“…Thus, wide bands and ultra-wideband (UWB) systems are promising alternative devices. The recent narrow-band [21][22][23][24][25] antennas with a lower gain and a bigger size are designed with a complicated structure even though the Photonic Band Gap (PBG) structure could be a promising periodic structure to compensate those drawbacks. There are wide-band and ultra-wideband antennas in [26][27][28][29][30][31][32][33] with less working BW, and a lower gain along with more substantial dimensions compared to the operating frequency for underwater communications.…”

The increasing needs of free licensed frequency bands like Industrial, Scientific, and Medical (ISM), Wireless Local Area Network (WLAN), and 5G for underwater communications required more bandwidth (BW) with higher data transferring rate. Microwaves produce a higher transferring rate of data, and their associated devices are smaller in comparison with sonar and ultrasonic. Thus, transceivers should have broad BW to cover more of a frequency band, especially from ultra-wideband (UWB) systems, which show potential outcomes. However, previous designs of similar work for underwater communications were very complicated, uneasy to fabricate, and large. Therefore, to overcome these shortcomings, a novel compact elliptical UWB antenna is designed to resonate from 1.3 to 7.2 GHz. It is invented from a polytetrafluoroethylene (PTFE) layer with a dielectric constant of 2.55 mm and a thickness of 0.8 mm. The proposed antenna shows higher gain and radiation efficiency and stability throughout the working band when compared to recent similarly reported designs, even at a smaller size. The characteristics of the functioning antenna are investigated through fluid mediums of fresh-water, seawater, distilled water, and Debye model water. Later, its channel capacity, bit rate error, and data rate are evaluated. The results demonstrated that the antenna offers compact, easier fabrication with better UWB characteristics for underwater 5G communications.
