CPW Fed Antenna with Ultrawide Bandwidth for Wearable Applications

Abstract

A novel coplanar waveguide fed antenna for wearable applications is discussed in the paper.
Primary focus is on the wide bandwidth so that they can carry data on wide range of
frequencies. The ultra-wideband antennas can transmit a great amount of information across
a wide frequency range. The presented configuration has 30.5 x 25mm dimensions using Zelt
as the substrate with a substrate thickness of 1.6mm. Zelt is a flexible fabric material used for
wearable applications with relative permittivity of 1.05. It is a high-quality nylon based
substrate. It is durable, tear resistant, and is easy to form and handle. The antenna was
designed using the ANSYS HFSS platform. Appreciable return loss was obtained for the
antenna in the required bandwidth. The obtained return loss, VSWR and radiation patterns
are in very much compliance with the existing wireless standards.
