The paper analyzes a possibility of using the verified by international scientific organizations calculation methods of signal attenuation and field intensity along the radio wave propagation path for assessment of electromagnetic compatibility of wideband radio monitoring stations equipped with radio electronic facilities of various purposes.
A concept of providing wireless power supply with microwave beam for pilotless aircrafts is introduced. The article presents justification of the choice of focusing type electromagnetic radiation (EMR) based on the requirements to the wireless power transmission (WPT) system. The features of the EMR focusing on receiving-rectifying antenna (rectenna) installed on movable objects are considered. With...
The paper deals with the antenna system of Vivaldi type for a ground penetrating radar (GPR), which is optimized for using ultrawideband pulse signals of subnanosecond range. Results of development and experimental investigation of characteristics of the antenna and the entire GPR antenna system have experimentally demonstrated the possibility of detection and localization of subsurface cracks in...
Formulae determining the location of elementary impedance strips as well as the volume of reactive, active and complex impedance distributed on them that secure the maximum decoupling between receiving and transmitting antennas have been found.
