A design of a wearable antenna for wireless local area network (WLAN) applications is presented in this study. The antenna consists of a button shape outer cylindrical structure and an internal central via connected to a top disc at one end and the metal ground plane at the other. The overall size and shape achieved are those of a standard metal jeans button which camouflages the antenna for wearable applications. The proposed wearable antenna is designed for 2.4 and 5GHz with monopole-type radiation patterns at each band. This allows for transmission to other worn devices on the body. An investigation into the measured permittivity of cotton denim is presented and a section on the equivalent circuit modelling of the antenna and the fabric is given.
