Wearable technology has recently attracted much interest for various uses. An essential component of the wearable system is the wearable antenna. Textile and non-textile materials have both been used to create wearable antennas. Textile antennas are very useful and widely used nowadays, particularly in body-worn applications monitoring health parameters. Fabricated using microstrip technology, textile antennas have various benefits, including small size, lightweight, simple fabrication, and ease of wear. In this study, a microstrip antenna is created utilizing a substrate made of jeans. It wor

We analyze square antennas with one and quasi-two sources to reveal the relationship between loop and plate antennas. First, using the moment method, one-source antennas with corner truncation are investigated versus antenna height above the ground plane. As the height increases, the CP wave bandwidth of the plate antenna increases 17% for a 3 dB axial ratio criterion, whereas the loop antenna’s bandwidth remains less than 3%. Next, we study quasi-two-source antennas without corner truncation versus antenna height. The plate antenna’s bandwidth is found to reach 30%, which is wider than that o

Modular-assembled antennas represent an effective solution for the challenge of building super-large antennas in orbit. To investigate the impact of errors in modular-assembled antennas on their radiation characteristics, this study proposes definitions for these errors and presents methods for addressing them during the engineering design phase. The sources of errors in the modular antenna units are identified, and formulas for the error contributions of each module are derived. Based on this error analysis, a relationship between the errors of individual modules and the overall assembled ant

The RF front-end performances in the far-field condition of reconfigurable antennas employing two commonly used RF switching devices (PIN diodes and RF-MEMS switches) were compared. Two types of antennas (monopole and slot) representing general direct/coupled feed types were used for the reconfigurable antennas to compare the excited RF power to the RF switches by the reconfigurable antenna types. For the switching operation of the antennas, a biasing circuit was designed and embedded in the same antenna board, which included a battery to emphasize the antenna’s adaptability to mobile devices.

Abstract Body Area Networks (BANs) have gained significant popularity in recent years, leading to a substantial rise in the demand for wearable antennas. Printed antenna on the flexible substrate can be an excellent choice for wearable since it can be used as a smart garment (i.e. shirt, T-shirt, or jacket). Unlike rigid antennas, the fabrication and measurement procedures for wearable antennas are particularly critical and sensitive. In BANs, the presence of the human body presents another significant challenge such as structural deformation (like bending). This paper has provided an overview

Research on multiple antenna systems has been a hot topic in recent years due to the demands for higher transmission rate and more reliable link in rich scattering environment in wireless communications. Using multiple antennas at both the transmitter side and the receiver side increases the channel capacity without additional frequency spectrum and transmitted power. However, due to the limited space at the size-limited terminal devices, the most critical problem in designing multiple antennas is the severe mutual coupling among them.

Physical deformation mechanisms are emerging as compelling and simple ways to adapt radio frequency (RF) characteristics of antennas in contrast to digital steering approaches acting on topologically fixed antennas. Concepts of physical reconfigurability also enable exceptional capabilities such as deployable and morphing antenna arrays that serve multiple functions and permit compact transport with ease. Yet, the emergent concepts lack broad understanding of effective approaches to integrate conformal, electrically conductive architectures with high-compliance foldable frameworks. To explore

Abstract Recently, aperture antennas that have the ability to change their reflector shape through the usage of piezoelectric actuators have been studied. The results show that those antennas can exhibit beam steering and beam shaping in the far-field. However, the previous studies have been confined to cylindrical shape antennas. This study examines the use of “doubly curved” antenna structures to achieve better performance in controlling an antenna’s coverage area. The spherical antenna is modeled as a shallow spherical shell with a small hole at the apex for mounting. Following Reissener’s

For high electromagnetic performances, large space truss antennas should have reflector surface with an extremely high precision. Due to the varied load and some random disturbances, active control strategy is always used in the kind of structure for the precise surface. For the improvement of the electromagnetic performances, an electromechanical synthesis optimization model of space antenna structure systems is developed based on the antenna’s characteristics, which adopts the axial gain of antenna and power consumption of actuators as the objective functions, and structural material strengt

This paper presents a comprehensive review of ultra-high frequency (UHF) radio frequency identification (RFID) tag antennas. Due to multiple benefits, RFID technology has supplanted conventional methods of identification like barcodes, magnetic stripe cards, and smart cards. The size of the antenna plays a crucial role in determining the overall dimensions of the RFID tag, making antennas typically low profile and compact. It is acknowledged as an innovative approach for tracking because of its affordable price, passive wireless power transfer capabilities, versatility, and non-line-of-sight c
