Bending analysis of Compact geometry Monopole Antenna for Wearable Applications

This work describes a compact monopole antenna design including bending analysis. The antenna has a variable return loss of -41dB and a bandwidth of 1422MHz for the lower microwave band resonance of 4.52GHz. The bending analysis along the X, Y axis planes are performed at different phases. V2X high-speed wireless communication, 5G WLAN, 5G-NR frequencies, fifth-generation Sub-6GHz (5G) smartphone apps, and C-band wearable applications are all intended uses for the designed antenna. With a thickness of 24 x 29 x 0.254 mm³, the substrate exhibits compact geometry. Through simulations employing tissue that resembles a human arm model, a gain value of 3.64dBi with SAR values that remain within the allowable range are also attained.
