A Dual Band Belt Antenna

A novel wearable antenna for wireless communications is presented in this paper. This paper has discussed the possibility of employing a belt buckle as an antenna, bringing benefits such as removability and the ability to hand portable wireless devices from the belt itself. The antenna consists of a belt buckle, hinge, denim waist band and electrical connections. The antenna was fed by a microstrip transmission line on the denim substrate with the antenna placed on the other side of the textile band. The prototype achieves wide band, dual frequency operation and is able to cover the 2.45GHz and 5.25 GHz bands necessary for Bluetooth/WLAN and IEEE 802.11 standards.
