As such, it is suitable for integration into an assembly line, where substrate samples are first quickly characterized before being used in the production of the actual antennas. It is shown that the proposed technique is fast, precise and non-destructive. Next, the method is applied to several textile materials of interest. The approach is validated by characterizing the high-frequency laminate on which the antenna is implemented. Then, the comparison between modeled and measured frequencies yields the electromagnetic properties of the material. First, the two frequency values at which the simulated return loss peak of the fixture crosses a given threshold value are modeled as polynomial functions of the materialвЂ™s relative permittivity and loss tangent.

An inset-fed patch antenna operating in the vicinity of the 2.45 GHz Industrial, Scientific and Medical frequency band enables us to quickly estimate the properties of a given substrate sample. Therefore, we propose a novel approach that compares simulations and measurements performed by a resonance-perturbation method. An additional detection by Geostationary Orbit Search and Rescue (GEOSAR) satellite confirmed the successful operation of the body-worn antenna system.Д®lectromagnetic characterization of materials applied in wearable components is of paramount importance for the design and production of reliable devices. In both cases, low-earth orbit search-and-rescue (LEOSAR) satellites detected the distress signal within minutes, and accurately resolved the location. The antennas were used in field tests organized in cooperation with the local Cospas-Sarsat search-and-rescue authorities. The electrical and mechanical requirements for antenna materials and antennas were derived from the Cospas-Sarsat system requirements, possible antenna platforms, and the maritime operational environments. The modular approach adopted in the work allows different antenna configurations for different platforms.

This paper summarizes the design, development, and verification for a body-worn antenna system interfaced with commercial Cospas-Sarsat personal locator beacons (PLBs), where the implemented system is integrated within an inflatable live vest. The Cospas (Cosmicheskaya Sistyema Poiska Avariynich Sudov)-Sarsat Search-and-Rescue (SAR) satellite system provides distress alert and location data to assist rescue operations at sea, in the air, or on land.
