20130144554 | MICROWAVE PROBE FOR FURNACE REFRACTORY MATERIAL - Disclosed is a system and method to aid in these inspections that avoid the disadvantages of the prior art. The system and method are operative to take thickness measurements of, and thus evaluate the condition of, materials including but not limited to refractory materials, operating in frequency bands that result in less loss than previously known technologies, and utilizing a system configuration and signal processing techniques that isolate the reflected signal of interest from other spurious antenna reflections, particularly by creating (through the configuration of the antenna assembly) a time delay between such spurious reflections and the actual reflected signal of interest, thus enabling better isolation of the signal of interest. Still further, the antenna assembly is intrinsically matched to the material to be probed, such as by impedance matching the antenna to the particular material (through knowledge of the dielectric and magnetic properties of the material to be evaluated) to even further suppress spurious reflections. | 06-06-2013 |
20140340279 | ADAPTIVE ANTENNA FEEDING AND METHOD FOR OPTIMIZING THE DESIGN THEREOF - Disclosed is an antenna feeding system and method to optimize the design of the feeding system to feed an antenna made of a resistive sheet.

The system is designed to reduce a convergence of radiofrequency currents that may create a localized high density current concentration, such as “hot spots” and “pinch points,” on the resistive sheet, by a sufficient extent so as to prevent power losses that substantially decrease the radiation efficiency of the antenna as compared with feeding systems designed using traditional design techniques. | 11-20-2014 |
20150061961 | DESENSITIZED ANTENNA AND DESIGN METHOD THEREOF - Disclosed is an antenna system and method to design a desensitized antenna element. The system and method are operative to design a configuration of an antenna to overcome a number of operational conditions in which the frequency response of the antenna element may be uniquely or significantly detuned or offset or in which undesired noise, signal interference, or electromagnetic coupling effects may affect or be induced by the antenna element. These operational conditions may include the presence of any combination of user body parts, conductive materials, or dielectric materials as well as neighboring electronic systems or other sources of undesired noise, signal interference, and electromagnetic coupling. The system is designed to mitigate adverse effects, when operating in a potentially antenna-detuning environment or under conditions that may affect other systems or be susceptible to being affected by other sources, by using a desensitizer element comprising at least one electrical circuit component. | 03-05-2015 |
