“…The addition of slots in the radiator patch modifies the current on the patch [6,45,47,51], leading to better antenna performance: (I) BW enhancement [6,36,43,44,47,52], (II) dual-band or multi-band resonant frequencies [44,[51][52][53][54], (III) miniaturization of the overall antenna size [6,36,45,53], (IV) antenna frequency tuning [45,[51][52][53][54][55], and (V) circular polarization [54].…”

“…Their fabrication at lab scale is simple, their compactness in terms of the overall volume is good, and their impedance matching is easily obtained with capacitive coupling radiator patches [7] or adjusting the position of the feeding point [41,44,52,53,55]. The main BW enhancement techniques that do not change the antenna topology are based on slots in the radiator patch [6,37,44,45,47,48,50,52,53,55] or on parasitic elements close to the radiator patch [7,36,43]. This feeding technique is not ideal for real textile applications that are expected to be flexible and comfortable, since the rigid coaxial probe is part of the antenna and can not be removed after antenna testing.…”

“…The advantages of these topologies are: (I) The increased isolation between antenna and wearer without the need for a large ground plane, (II) low-cost and low-loss implementation, (III) being compact and low profile [44], and (IV) their miniaturization possibilities by exploiting the symmetry of the field distribution of the resonant modes, like a half-mode or quarter-mode SIW [45]. The body isolation is significantly increased when compared to conventional microstrip antennas with larger ground planes and smaller dimensions [53].…”

Fully textile smart wearables will be the result of the complete integration and miniaturization of electronics and textile materials. Off-body communications are key for connecting smart wearables with external devices, even for wireless power transfer or energy harvesting. They need to fulfill specific electromagnetic (EM) (impedance bandwidth (BW), gain, efficiency, and front to back radiation (FTBR)) and mechanical (bending, crumpling, compression, washing and ironing) requirements so that the smart wearable device provides the required performance. Therefore, textile and flexible antennas require a proper trade-off between materials, antenna topologies, construction techniques, and EM and mechanical performances. This review shows the latest research works for textile and flexible planar, fully grounded antennas for off-body communications, providing a novel design guide that relates key antenna performance parameters versus topologies, feeding techniques, conductive and dielectric textile materials, as well as the behavior under diverse measurement conditions.

“…These antennas have gained much attention due to their robustness, small profile, flexibility, simple design, light weight, ease of integration into the garments, and its sustainable optimum performance [2,3]. Because of these advantages, wearable textile antennas have a wide range of applications in the area of medical stream [3][4][5], public safety [6], emergency rescue systems [7], navigation [8], entertainment, aeronautics, tracking a person in defense and mining [9,10] and have also found a solution for the implementation of wireless body area network (WBAN) [2,[11][12][13], on-offbody [14][15][16][17], and Body Centric wireless communications (BCWC) [18][19][20]. In open literature, several topologies have been presented for the development of the wearable textile antennas which include 3D printing technology [21,22], PIFA [11,23,24], IIFA [25], Substrate Integrated Waveguide technology (SIW) [14,16,26,27], aperture coupled [28,29], microstrip patch [16,17], CPW fed [2,21,30,31], EGB based [4,32,33], meta material based…”

This paper presents design analysis of a compact CPW-fed Wearable Textile Antenna with Dual Band notched characteristics for UWB applications. The proposed wearable textile antenna is designed on two different dielectric substrates; leather and denim with copper foil as conducting element. The performances of the designed textile antenna are compared on two substrates. Band-notched filtering characteristics are achieved by inserting semicircular split ring resonators on the conducting element. The first notch band is obtained from 2.3-2.5 GHz for Bluetooth application band, and the second notch band is obtained from 3.3-3.6 GHz for WiMAX application band. The simulated and measured frequency results show that the antenna has an impedance bandwidth of 1.8-10 GHz and reflection coefficient less than −10 dB, except at the two eliminating bands. The proposed antenna is designed and simulated using Ansys HFSS Electromagnetic Simulator. The prototype of the antenna has been developed on the denim substrate, and its performance is measured and compared with the simulated ones.

“…UWB textile antennas can be easily integrated into the garment, due to their small size and flexible construction. Textile materials are used as non-conductive substrate material or metallic radiating element for wearable antenna [17]. The use of non-conductive textile fabric as a substrate material helps to reduce antenna surface wave losses and increases band width with low dielectric constant [18].…”

This paper presents the design and analysis of a compact and flexible textile antenna for wireless body-area network systems. The presented antenna operates at a frequency range of 2.2 GHz to 17 GHz and covers the UWB frequency band. The antenna is designed from a jeans textile substrate with attractive features such as flexible and low dielectric properties. Copper tape was used for the radiator patch and ground plane of the antenna. The dimensions of antenna are 45 mm x 60 mm x 1 mm. In this study, the UWB antenna successfully evaluated the return loss (S11) and radiation pattern parameters under the planar condition and various bending conditions. It has been observed that the simulation result values of the antenna are suitable for UWB WBAN applications under planar condition and different bend conditions. Index Terms-Bend effect, textile antenna, wearable antenna.
