Abstract
A three dimensional (3D) fractal structure with H as the mother element is hereby disclosed. Such a 3D structure can act as selective total microwave reflectors or selective microwave filters in transmission. When excited through current injection, such a 3D fractal structure can act as highly efficient antenna for radiating or detecting pre-determined microwaves, with the relevant wavelength much larger than the size of the radiation or detection structure.
