“…From Figure B, it can be obtained that the radiation of the tag antenna along the –z‐axis is stronger than the +z‐axis, the maximum gain at 908 MHz is 1.52 dB. The dielectric resonance takes place because of the high dielectric constant and the low conductivity of water …”

A novel ultra-high-frequency (UHF) radio frequency identification (RFID) tag antenna has been proposed in this article, which can be mounted on the surfaces of the human body and water. The proposed antenna is realized by an elliptical structure, whose long and short axes are 72 and 30 mm, respectively. The tag antenna consists of an elliptical loop radiation element, microstrip feed lines, arc matching networks, and tuning patches. We have analyzed the antenna radiation characteristics influenced by the structural parameters of the antenna and the thicknesses of the human body and water. The simulation and measurement results show that the proposed antenna can operate steadily on the surfaces of the human body and water with good conjugate impedance matching. The maximum measured reading range of the tag antenna on the surfaces of the human body and water can reach 5 and 7 m, respectively. The novelties exhibited in the proposed antenna include an elliptical structure, the stable performance on the surfaces of the human body and water, small size, and long reading range.

“…However, due to the conductivity of the human body, the backward radiation in the direction -z is decreased. On the other hand, when the antenna is mounted on the surface of a water-filled container, due to the high dielectric constant of water, dielectric resonance will occur, causing greater backward radiation [20].…”

A novel ultra‐high frequency radio frequency identification tag antenna designed for multi‐usage is proposed in this study, which can work on the human body, blood bags, and water‐filled container as well as free space. The tag antenna is fabricated on the F4B‐2 substrate, whose relative permittivity is 2.65 and dielectric loss tangent is 0.002. The radiation unit is formed by four main circular loops, two semicircle loops, and four round arcs, all these loops and arcs are surrounded by an elliptical loop located on the outer edge of the substrate. The antenna has an elliptical structure, whose long axis and short axis are 76, 32 mm, respectively. In different applications, the presented antenna maintains a stable operating frequency and has good conjugate impedance matching with the tag chip.

“…Based on several studies, the flat patch antenna is not suitable for antenna to operate for UWB operating frequency [35][36][37][38]. Therefore, the UWB conformal antenna is proposed [39][40][41][42]. A single patch antenna for UAV used at ultra-wideband (UWB) frequencies (2.9 GHz to 15.9 GHz) has been designed by Balderas et al, [43].…”

The wide-ranging Unmanned Aerial Vehicle (UAV) applications making them be one of the Internet of Things promising technologies. The vast potential of monitoring and surveillance for public safety threats using drones be a current issue for researchers. Antennas play an important part in UAV to create reliable communication links. There are different types of antennas that can be used for UAV application depend on antennas size, efficiency, gain, angle of radiation pattern, polarization, etc. This paper mainly focuses on patch antennas for UAV applications. In general, there are two types of patch antenna is described which are single patch antenna and array antenna. The review of patch antennas can be a useful guideline to choose or design antenna for UAV applications in the future.
