Negative Refraction of Double F-Shaped Resonator at K-Band

A single sided double F-shaped resonator is investigated in this paper. The work intends to examine the response of the proposed structure in an array printed on single side of a lossless substrate. This work also intends to miniaturize the cells and examine its response at K-band for beam tilting and for using the metamaterial as a dielectric in different antennas.
