“…One of the important requirements of WBANs is to have an antenna with wider bandwidth. In [21], De et al depicted that the partial ground plane antennas exhibit broader bandwidth, and in [22] Raj et al showed that antennas with defected ground plane structures like slotted ground plane have a wider bandwidth.…”

Wearable textile antennas have obtained remarkable attention in various medical fields due to their ease of integration and flexibility. This paper puts forward an Ultra Wide Band (UWB) Compact Textile Wearable Antenna (CTWA) for Wireless Body Area Network (WBAN) applications. The proposed antenna is a semicircular slotted elliptical antenna with an L-shaped stub and a partial defected ground plane. The antenna is fabricated on denim jeans (ϵr = 1.77) and has an overall dimension of 27 × 28 × 0.7 mm with an operating frequency range 3.01-15.98 GHz, radiation efficiency of 83.5-90.11%, and maximum gain of 5.81 dBi. Structural deformation studies including human body loading of the antenna are carried out, and the performance of the antenna is found to be stable. The proposed antenna has a low profile and high fractional bandwidth (137%) compared to the UWB wearable antennas reported in the literature. The calculated Specific Absorption Rate (SAR) of the antenna at the frequencies 4,7 and 10 GHz are 1.2, 1.06, and 1.58 W/Kg, respectively, which lies within the FCC (Federal Communications Commission) standard. The proposed CTWA is compact, flexible, wearable, and robust, which makes it suitable for on-body WBAN applications.

“…It is desirable to build a patch antenna that covers two or three nearby frequency bands in certain wireless communications applications. For example, a base station antenna may be required to simultaneously provide wireless access services for both WCDMA (1.92 2.17 GHz) and WiMAX (2.50 2.69 GHz), while rejecting most of the frequencies between the two bands [1][2][3]. In this case, the center frequency ratio is 1.27.…”

The suggested antenna is based on a patch including complementary split-ring resonators in the ground plane and a truncated corner slot. The antenna displays four operational bands in this manner, and its resonant frequencies can be individually adjusted by adjusting the ground plane resonator structures and the patch slot's dimensions. Furthermore, the antenna displays a notch-band feature at 10.7 GHz as a result of the complementary split-ring resonator structures' anti-resonant behavior. Four X-band operating bands are displayed by the suggested antenna, together with their respective absolute and relative bandwidths. 7.0–7.2 GHz (200 MHz, 7.8–8.0 GHz (200 MHz),8.3–8.4 GHz (100 MHz) and 8.7-8.9 GHz(200MHz) s. The antenna is simulated in order to achieve desired gain, omnidirectional radiation patterns, and return loss characteristics.

“…The monopole antennas are specially used in UWB applications and circularly polarized are attracting more during the rapid development of wireless systems. Researchers are reported many simple structures with multi bands configuration which is used in wireless and satellite communication [1][2][3][4][5][6][7]). A compact multiband CPW monopole structure was presented, where a square ring with a T slot is used for achieving the wireless frequency.…”

A super wideband monopole antenna design for microwave and advanced wireless applications inthe frequency range of 2.2 GHz to 27.06 GHz. At first, a circular resonator with a ring dimensionis used to achieve a wideband range of frequency with a band rejection characteristic in the lowerband. Where the antenna provides broadband from 2.2 GHz to 27.06 GHz with four notch bandscovering 12.26- 14.44 GHz, 17.39–19.60 GHz, 2.69–4.36 GHz, and 5.5–7.14 GHz. These notch bandfrequencies are productively used to evacuate undesired interference of different wireless frequencies.Additionally, six symmetrical tiny circle stubs are introduced in the ground plane to improve the overallcharacteristic without notch bands. The combination of the ring patch with the line feed broadensthe stable radiation, super bandwidth, and stable gain characteristics. The overall electric size of theantenna is 0.41 × 0.35 × 1.5230where the maximum gain is 6.4 dBi in between the higher frequencyband and 4 dBi from 2.6-5.7 GHz. The proposed antenna exhibits a novel structure and achieves a widebandwidth without using any external electronics components. The overall fractional bandwidth ismore than 166% and excellent performance enters the wireless frequency band. The proposed structurewas designed and fabricated to be experimentally validated and could be applied in various wirelesscomponents and applications.
