It has dimensions of 40.5 x 23 x 0.97 mm 3 . The polygon-shaped patch is modified to achieve ultra-wideband frequencies using partial ground as 16.5mm and a periodic vertical slot of 13x2 mm 2 structure in defected ground structure to enhance the wide bandwidth of 2.6-11.1 GHz. Using a transmission line equation and a microstrip line feeding method, the resulting antenna operates at a biomedical frequency in open space and on the body-worn case with multi band i.e. 3.1 and 5GHz. The deformation process works well for the proposed antenna without affecting its actual bandwidth with 20 to 60 mm radii. Additionally, the proposed antenna operates at 5GHz for Wi-Fi with 3.67dBi gain, -35.1dB as S11 which is suitable for commercial applications. CST Microwave Studio was used to simulate the antenna and fabricate it for testing. General Terms: Textile antenna for wireless body area network at ultra-wide band frequency for biomedical applications. Keywords: DGS, Flexible Fabric, Microstrip Antenna, UWB, WBAN. ░ 1. INTRODUCTION In wireless communication systems antennas are one of the basic components since they are a key component in the transmission and reception of data. Different antennas are used in modern communication to transmit and receive data for portable wireless devices, radar applications, bio-medical applications, and more [1]. Because of their inexpensive cost and ease of construction, microstrip patch antennas (MPAs) are popular for a variety of applications. Antennas of this type are commonly employed in biomedical applications [2].The Antenna is placed on the human body’s surface. The foremost restrictions of the MPA’s are the single working frequency with narrow bandwidth, size of the antenna, and low gain. The constraints of MPA are addressed using a variety of ways. Furthermore, the microstrip patch antenna array structure is used to achieve multi-band operation, and a novel DGS is used as the ground to increase the antenna's performance. The federal communications commission (FCC) allowed the viable usage of frequency bands for ultra-wideband systems ranging from 3.1 to 10.6 GHz when it first introduced ultra-wideband in 2002. The UWB antennas can be used to cover mobile and wireless services [3-5] while also reducing system complexity by reducing total device size and cost. The fundamental goal of the antenna design is to increase performance and gain while maintaining high radiation efficiency at UWB.A unique ultra- wideband wearable antenna for electronic-textile applications with a permittivity of 1.45 and operating at the frequency of 3.1- 11.3GHz UWB was developed utilizing a permittivity of 1.45 for felt material and operates at the frequency of 3.1-11.3GHz UWB. An ultra-wideband monopole antenna base on DGS 2021[6]. [7] discussed about a system, a low power area reduced and speed improved serial type daisy chain memory register also known as shift Register is proposed by using modified clock generator circuit and SSASPL (Static differential Sense Amplifier based Shared Pulsed Latch). This latch-based shift register consumes low area and low power than other latches. There is a modified complementary pass logic based 4-bit clock pulse generator with low power and low area is proposed that generates small clock pulses with small pulse width. The antenna was implemented with a cotton substrate with a permittivity of 1.4 that can function at frequencies ranging from 10.08 to 12.98 GHz and 2.59 to 6.67 GHz, backing up a variety of communication services in the X, C, S, and Ku bands with a gain of 7.4 dBi. In addition to resonance at 2.9 GHz, 9.1 GHz with a S11 of 34.84 dB, 33.74 dB, respectively, the proposed MCP antenna achieves an impedance bandwidth of 8.1 GHz (2.5–10.6 GHz) with a reflection coefficient reference line of 10 dB. Four dumble-shaped slots are used to increase antenna bandwidth and gain. The radius of a circular patch is determined by parametric analysis for UWB frequency tuning. [8].
