Dual Band Button Antennas for Wearable Applications

A novel structure for wearable WLAN applications is presented. This antenna is a top loaded monopole and is shaped as a button. The antenna is easily disguised and is less sensitive to the clothing fabric than printed patches. The antenna is dual band at 2400MHz and 5200MHz with the omni-directional radiation patterns required for transmission with other wearable devices located both on and off a user’s body.
