Abstract
A flexible antenna capacitively coupled to related circuitry components for an active wearable data transceiver electronic location and identification device. Wearable data transceivers (WDXs) are employed as bracelets, badges, and may be incorporated with back pack straps and clothing at locations such as collars, cuffs, and hems. They employ various colors. Active transceiver communication devices are also mounted on objects for real time location tracking and identification. Body-mounted WDXs match the body with the antenna for sending and receiving signals. WDX power includes coplanar battery cells and circuitry has radio transmitter and radio receiver components.
