The paper explores the sensitivity of a wide band UHF textile antenna for reception of digital television and discusses the performance of the antenna when submitted to curvature or the presence of the body. Despite dimensions that are somewhat large for a human body, the study shows that the antenna performs well in curved situations, showing little change in return loss when crumpled, rolled, and worn on chest and arm. The antenna is also robust to changes in thickness and permittivity of the substrate, which is an advantage as the same design could potentially be directly applied to a range of textile materials with only minor modifications to the original design.
