Patent abstract
A wearable article of clothing and the like is configured to be worn by a person underwater or underground; An antenna with at least one loop, is coupled to the wearable item. The antenna provides transmission or receipt of electromagnetic signals and has a size and geometry that maximizes antenna transmission area while minimizing a restriction on movement by the person wearing the wearable article. The antenna carries an alternating current that provides conductive attenuation and has three different field components. Each field component has a different geometric loss when moving a distance r from the antenna. R is a propagating distance from the antenna.
