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.

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

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.

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

Considering the technological enhancements nowadays, antennas tend to be smaller in order to be easily integrated in devices. The most used antennas today in small high-tech devices close to the human body are planar antennas. In this paper, a Yagi Uda planar antenna operating at a frequency of 2.4 GHz is HF analyzed and optimized by increasing its bandwidth and gain while maintaining its initial dimensions. The methods used to optimize the antenna’s operation are the use of different dielectrics, different numbers of directors, and different dimensions for directors, placing new conductor ele

Background. The creation of an antenna system consisting of two spiral structures for the 2,4 GHz and 5,8 GHz frequency bands is caused by practical needs determined by the results of using drones to monitor the environment. The proposed technical solution was based on a study of known antennas for the 2,4 GHz (right circular polarisation) and 5,8 GHz (left circular polarisation) frequency bands. Due to the mismatch of the polarisation of the electromagnetic wave and the antenna, losses of up to 20 dBp can occur. To reduce losses, a design of spiral antennas with the ability to change the pola

An empirical method for simplified dimension estimation of patch antennas is proposed in this work based on characteristic mode analysis (CMA). This method involves generating formulae to calculate substrate-independent antenna patch widths produced from the antenna’s characteristic angle. This enables the definition of a relationship between the characteristic angle and the natural resonant frequency of an antenna structure, bridging the changes of resonant frequencies contributed by possible variation in substrate properties. From here, the end ‘calibrated’ results can be used to generate sp

The antenna's performance was tested at three evenly separated frequencies: 60 GHz within the V-band region, 80 GHz within the E-band region, and 100 GHz. Simulation exhibits satisfactory results in terms of gain and efficiency, although the efficiency falling tendency for higher frequency persists. As millimeter wave antennas have miniature-like dimensions and low penetration depth into human body layers, the performance of these antennas is les
