Abstract
An ultra-broadband antenna is incorporated into an electrically nonconductive garment. The antenna includes first and second RF elements attached to the garment so that a gap exists between them, where the RF elements each form a band when the garment is worn by a wearer. RF and ground feeds are electrically connected to the first and second RF elements, respectively. A shorting strap electrically connected between the first and second RF elements on the anterior side of the garment generally opposite the feeds helps match the antenna impedance to an external signal source. A gap between the RF elements provides a voltage difference between the RF elements when the antenna is energized. Electrically conductive straps are electrically connected between the anterior and dorsal regions of the first RF element that extend over the shoulder region of the garment. An impedance matching circuit electrically connected between the first RF element and the RF feed is used to match the impedance of the antenna with an external device for a particular operating bandwidth. The garment may be a vest or pullover garment suitable for being worn on a human torso.
