Abstract
A passive device is taught which diverts radio-frequency electromagnetic energy from an original path to a new path at a 90.degree. angle. The device eliminates the large reflective sheets which characterize prior art devices for the same purpose. The device utilizes a modified Yagii-Uda parasitic array to excite a cross-dipole element which reradiates the energy along the new direction. A particular application is shown for placing the device in or on a wall or the like for unobtrusive diversion of energy.
