This article explores the design and analysis of a novel ultra‐wideband (UWB) antenna for body‐centric applications. The designed antenna consists of circular ring structured radiating element with 24 spokes, which resembles the shape of Ashoka chakra (Indian National flag emblem). The antenna placed on the semi flexible RT/Duroid 5880 with dielectric constant of 2.2 and occupying the dimension of 30 × 25 × 0.8 mm3. The present design aims at optimizing the antenna structure to cater UWB operating spectrum (3.1‐10.6 GHz) with a novel patch shape, which looks like the Ashoka chakra. The proposed antenna is analyzed by placing on three‐layered human phantom model and examined on head, arm at three of its operating frequencies. The maximum specific absorption rate (SAR) is found to be 1.23 W/kg and 1.29 W/kg when computed at arm and head of the human body respectively. The SAR values are observed under those conditions are satisfying the international safety standards such as FCC & IEEE C95.1:2005 & ICNIPR. Analysis of system savant (ANSYS Savant) radiation performance characteristics are also studied by placing the proposed antenna on virtual human body environment.

Abstract-A novel and compact conformal printed dipole antenna with geometrical modifications in ground plane is proposed in this paper for 5G based vehicular communications and IoT applications. The proposed antenna consists of a printed dipole as defected ground structure and a staircase structured offset fed integrated balun to attain wideband operation. It yields a better −10 dB impedance bandwidth of 17.65 GHz and 2.24 GHz over the frequency ranges 24.3 to 41.95 GHz and 49.91 to 2.15 GHz. Antenna projects the peak gain of 6.81 dB with 98.82% of peak radiation efficiency. The measured results of the proposed model are in good agreement with the simulation obtained from HFSS. The conformal models of the proposed antenna are developed to embed the antenna in different curved surfaces on vehicular body. The analyzed conformal characteristics of the antenna support excellent constant reflection coefficient with respect to planar structure of the antenna over the operating band at different angles.
