CPW Fed Antenna with Ultrawide Bandwidth for Wearable Applications

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
