In this study, a simple and compact antenna structure with dual‐port and dual‐mode operating in a single‐band is proposed for wireless body area network. This antenna is composed of a rectangular ring patch antenna, which is shorted in the outer edge to generate an omni‐azimuthal radiation pattern. This pattern is desired for the on‐body communication level. A substrate integrated waveguide cavity‐backed slot antenna is also located at the centre of the structure and provides the broadside radiation pattern desired for the off‐body communication level. The proposed antenna is fabricated and measured. The measured results are in good agreement with the simulated ones. The measured mutual coupling between two ports is less than −40 dB which is about 13.5 dB better than that of previous works.

“…The standard monopole antenna is a typical example of this, and it can be oriented to have vertical, horizontal, or inclined polarization. However, the conventional type monopole antenna is not convenient for the user to wear in a WBAN node and therefore many researchers have developed planar linearly polarized antennas to address this issue [48], [49], [50], [51], [52], [53], [54], [55], [56]. However, single-sided planar monopole antennas for WBAN suffer from the drawback of not providing conductive shielding on its backplane and hence the characteristics change when it touched the human body [57].…”

In this paper, a comprehensive review of the wireless body area network is provided. A review of the WBAN architectures, standard network topologies, and WBAN communication protocols is discussed in detail. Also, the security requirements of WBAN, security threats and types of attacks, and authentications used in WBAN are discussed. The paper also includes very detailed coverage of antenna types, antenna designs, and flexible antennas used in WBAN with some design considerations and comparisons. Some new energy harvesting technologies, materials used for energy harvesting, and energy management are also discussed. Energy harvesting and power management is an ever-growing area of research. Despite the fact that there are many nanogenerator-based energy harvesting methods, the demand for more efficient energy harvesting mechanisms is ever-increasing. The paper has an extensive discussion of energy harvesting and power management methods. Subsequently, some reviews of recent developments in wearable sensors and novel materials for developing wearable sensors are discussed. Finally, the application areas of WBAN are discussed INDEX TERMS Body area network, network security, wireless communication protocols, wearable sensors, energy harvesting, WBAN, flexible sensors, IoT.

A multiband and multi-mode antenna with circular polarized conical patterns is suitable for achieving desired spectral efficiency, increased capacity, and spatial diversity for IoT applications. However, simultaneous excitation of such circular polarized multiple Orbital Angular Momentum (OAM) modes through a single patch antenna is challenging due to the complexity of simultaneously fulfilling distinct requirements of each mode. In this paper, a ring patch antenna is designed to excite different OAM states at different frequencies simultaneously. First, characteristic mode analysis is used to analyze the possibility of simultaneous excitation of multiple OAM modes at corresponding frequencies through a simple ring patch antenna. Then, a dual port ring patch antenna is designed and fabricated to verify the capability of generating multiple OAM states at corresponding frequencies. Furthermore, it also presents the guidance to suppress unwanted OAM modes.
