Design of a Low-Profile Meander Antenna for Wireless and Wearable Applications

This proposed work discusses the design of printed meander antenna for Radar, mobile, and Wireless Local Area Network (LAN) applications. This meander antenna operates at a single narrow band from 4.29 to 4.31 GHz. The designed antenna is compact in profile, and the total dimension is 4 mm3 * 4 mm3 * 0.05 mm3. It is built on the substrate namely RT/Duroid 6010 having a relative permittivity of 10.2 and dielectric loss tangent of 0.0023. The proposed antenna is designed and simulated with the help of a 3D full wave simulator namely Ansys HFSS software. The performance parameters of the proposed antenna, i.e., reflection coefficient, VSWR, and the radiation pattern is plotted. The antenna shows a maximum reflection coefficient of − 21.8 dB at 4.3 GHz. Moreover, the size of the antenna is compact and it satisfies the SAR limits. Hence, the proposed antenna can be employed in wearable devices.
