In this paper, a grounded CPW‐fed multi‐band (GCM) wearable antenna for WLAN and medical application is presented. The multi‐band antenna operated at 2.4 GHz, 3.5 GHz, 6 GHz, and 6.7 GHz with a size of 58.5 mm × 62 mm. The grounded CPW consists of T‐shape silver fabric for radiating patch and defected rectangular ground plane. The antenna fabricated and tested on two different substrate, the non‐woven layer and cotton layer with dielectric constant 1.15, thickness 5 mm, and dielectric constant 1.65 with thickness 1 mm, respectively. The numerical and experimental result for different bending conditions are studied and also the antenna implementation on cotton layer using adhesive and sewing are compared. In different bending condition and different fabrication structures the result shows a good agreement between measurement results and simulations. The comparison confirms that the GCM wearable antenna could be a good candidate for wearable WLAN applications.

“…The use of the bio-inspired forms allows the development of compact structures with larger electrical perimeters, operating at lower frequencies [12]. Plant shapes were used in the development of some antennas, built in fiberglass, denim and transparent materials, such as cellulose acetate with Indio tin oxide film, operating in UWB applications [13], LTE bands at 700 MHz [12], 2G, 3G and 4G [14], and WLAN [15][16].…”

A flower-shape bio-inspired aperture-coupled antenna array for on-chip application, generated by Gielis formula, operating in industrial, scientific and medical (ISM) band at 60 GHz (57 GHZ to 64 GHz) is presented in this paper. The antenna proposed is composed of a transmission feed line followed by an aperture and patch element built in aluminum, with 2 micrometers of thickness, lying on two layers of silicon with 200 micrometers of thickness each. Dimensions of the antennas were calculated according to the effective wavelength for the resonance frequency at 60 GHz. Simulations were performed in the commercial software ANSYS® Electronics Desktop. The use of the bio-inspired flower-shape promotes more compact structures with greater perimeter, rearranging these shapes into an antenna array provided a gain and a bandwidth increase in the design, 3.11dBi and 2.86GHz, respectively, which resulted in a maximum gain of 8.82 dBi and a total bandwidth of 5.88 GHz.

Due to the recent miniaturization of wireless devices, the use of wearable antennas is steadily increasing. A wearable antenna is intended to be a part of the clothing used for communication purposes. In this way, a lower visual cost may be achieved. Recently, biologically inspired design, a kind of design by cross-domain analogy is a promising paradigm for innovation as well as low visual cost. The shapes of the plants are structures optimized by nature with the primary goal of light energy capture, transforming it into chemical energy. In this case, they have similar behavior to that of parabolic reflectors; this enables microwave engineers design innovative antennas using bio-inspired concepts. One of the advantages of using bio-inspired plant shapes is the design of antennas with great perimeters in compact structures. Thus, we have small antennas operating in low frequencies. This chapter presents the recent development in bio-inspired wearable antennas, easily integrated to the clothes and accessories used by the body, built in denim, low-cost flexible dielectric, and polyamide flexible dielectric, that is flexible with high resistance to twists and temperatures, for wireless body area network (WBAN) applications, operating in cellular mobile (2G, 3G, and 4G) and wireless local area network (2.4 and 5 GHz) protocols.
