Directivity, as a characteristic parameter of electromagnetic radiation source, could be used to classify different radiation sources, and the ESD events could be considered as typical sources. The parameter could be measured by electric field intensity radiating in all directions in the space. In this paper, we would build three basic antenna models which are all working at 3GHz and set cube receiving...
In this study, a dual-band high-impedance surface (HIS) structure and a dual-band monopole antenna were designed for 2.45 GHz and 5.25 GHz WLAN applications. This HIS structure was proposed as an electromagnetic (EM) protective sheet to reduce undesirable EM radiation of antenna. The effects of EM protection sheets including metallic plates, R-cards, and HIS on the specific absorption rate (SAR) and...
A novel design method has been developed to solve the Intra-EMC problem in mobile equipment. Recently, there has been a great deal of interest in the deterioration of receiver sensitivity due to the leakage of noise into a receiver circuit via the antenna. To solve this problem, we developed a design method in our previous studies that could estimate the optimal layout of a noise source according...
Electronic devices may act as unintentional radiators. Hence, the prediction of their breakdown behaviour is not possible by design. Instead, time-consuming measurements are necessary to determine their radiation patterns. Stochastic approaches help to do approximations, but need to be validated e.g. by numerical field simulations. In this paper, simulation objects are created by the use of the software...
GPGPU (General-Purpose Computing on Graphics Processing Unit) acceleration of calculation of fields radiated from MMIC passive components is studied. Radiated fields are calculated from reaction integral between source fields and radiation mode fields. Source fields are taken on a closed cuboid surface enclosing passive components and numerically obtained from the FDTD calculation of fields in the...
