ABSTRACT:
An antenna for a wrist transmitter or receiver carried in a wrist instrument is made of a wire mesh enclosed in an elastic fabric sleeve. The antenna wire is composed of a tubular mesh of individual copper conductors which are loosely woven, twisted, or braided in such a way as to permit lateral expansion and also to assume a flat configuration. In a preferred form of the invention, the wire is woven in a manner similar to that of a coaxial cable outer shield conductor. The method of making the expansion band antenna consists of inserting an unexpanded wire mesh within a stretchable elastic fabric sleeve, expanding the mesh within the sleeve, and then flattening the sleeve and wire mesh. The wire mesh may be expanded within the sleeve by allowing a stretched sleeve to relax while holding the unexpanded mesh within it, or it may be expanded laterally within the sleeve by a mechanical or pneumatic tool.
