| Popis: | Diffraction describes propagation into a shadow region, showing increasing attenutation with frequency. This behaviour is relevant to 5G systems where the mmwave frequencies have reduced coverage in non-line-of-sight areas of an urban environment. Here we seek to improve aroundthe-corner coverge by changing the electromagnetic nature of the corner. The simplest approach is to use a passive dipole scatterer placed at the corner. The coverage improvement is shown to be tens of dB above that of diffraction, and wideband. |
