“…Therefore, the use of an EBG structure as previously referred will improve the performance of the coplanar waveguide feed textile antennas. The process of designing a printed textile monopole antenna is presented in [84] which is lightweight and has a very simple structure to fabricate. One disadvantage of a printed monopole is that due to its short partial ground plane its performance is highly affected and degraded by the presence of the human body.…”

This paper will review the evolution of wearable textile antennas over the last couple of decades. Particular emphasis will be given to the process of embroidery. This technique is advantageous for the following reasons: (i) bespoke or mass produced designs can be manufactured using digitized embroidery machines; (ii) glue is not required and (iii) the designs are aesthetic and are integrated into clothing rather than being attached to it. The embroidery technique will be compared to alternative manufacturing processes. The challenges facing the industrial and public acceptance of this technology will be assessed. Hence, the key opportunities will be highlighted.

“…It can be comfortably worn and embedded in clothing due to its unobtrusive low-profile design. Other textile antenna types, such as PIFA or planar monopole antennas that achieve an omnidirectional radiation pattern are found in the literature [2,23]. The textile PIFA, exhibits a comparable on-body efficiency with the HMMPA up to 40%, although it fails to generate a strong surface wave propagation.…”

This study presents a wearable textile higher‐mode microstrip patch antenna (HMMPA) that has been designed to radiate omni‐directionally at 2.4 GHz Industrial Scientific and Medical (ISM) band. Emphasis is given to the fabrication process of the textile vias with conductive sewing thread that plays an important role in generating the optimal mode for on‐body radiation. The embroidery technique enabled a side‐fed low‐profile antenna which could be placed directly against the body. The proposed textile HMMPA antenna performance is compared with a probe‐fed HMMPA antenna fabricated with rigid copper radiating parts, for both free space and on‐body conditions. The on‐body antenna performance has been tested by performing near‐field measurements of the antenna on a full‐body specific anthropomorphic mannequin phantom in an anechoic chamber. Results show that the proposed textile HMMPA antenna with vias made from conductive thread can radiate on‐body with good efficiency while minimising the radiation in the broadside direction.

“…A patch length, L M = 0.25λ = 30.6 mm. The quarter-wavelength monopole has an excellent impedance matching and radiation performance in narrowband frequency [7,8]. To reduce the body coupling effect, TM is mounted 10 mm away from the body by using a thick foam with ε r ≈ 1.…”

This paper presents a novel study of evaluating non-ionizing effect of 2.45 GHz Wireless Body Area Networks (WBAN) radiofrequency (RF) electromagnetic fields (EMF) exposure on human physiological parameters and cognitive performance. The study aims to test the hypothesis whether exposure of 2.45 GHz WBAN radio electromagnetic fields may affect physiological parameters and cognitive performance of human. Twenty healthy volunteers are involved in the test and exposed to 2.45 GHz WBAN RF radiation, emitted by a planar textile monopole antenna. Physiological measures of body temperature, systolic blood pressure, diastolic blood pressure and heart rate are obtained, along with cognitive performance outcomes. Results indicated that no significant difference is observed in any of the three sessions (pre, exposure and post) for all physiological parameters, p > 0.05. Insufficient evident is found to indicate a difference in mean of all cognitive tests between WBAN RF and Sham exposure sessions, p's > 0.05.
