Design of Circularly Polarized Compact Size Wearable Antenna for UWB and 5G Application

Abstract

The proposed work shows the textile antenna design for the IEEE C band and future 5G communication. The proposed antenna #2 is compact with the size of 0.674λ × 0.712λ and it is designed using jeans fabric as the dielectric substrate of ε_r = 1.7 and thickness = 4 mm. The values of the S11 parameter of the antenna are below −10 dB, with a high gain of around 15 dB. The antenna is radiating with two frequency bands from 4 to 18 GHz and 24 to 58 GHz; in addition to this, the proposed antenna acts as a notch filter for the 8–12 GHz frequency band. The bandwidth achieved for the antenna is 4 GHz and greater than 34 GHz. The bending analysis of the antenna has been carried out at a radius of 80 mm and an angle of 90°. The value of simulated group delays for the proposed antenna is constant and varies from 0.02138 to 0.4251 ns, and the measured values range from 0.0507 to 0.6425 ns. The proposed antenna can be used for WiMAX, 5G and GPS applications.
