Elevation-plane beam tilting is demonstrated for a printed dipole antenna operating over 57–64 GHz. This is achieved using a 3x4 array of high refractive-index metamaterial (HRIM) unit cells. The unit cell comprises a modified H-shaped structure with stub loading to control the refractive index of the unit cell over a finite frequency range. Integration of the 3x4 array in the H-plane of a dipole antenna is shown to deflect the main beam by +30 degrees with respect to the endfire direction over 57–64 GHz. In addition, the proposed technique provides 5 dB gain enhancement.
