Beam tilting antenna using integrated metamaterial loading by Dadgarpour, Abdolmehdi, Zarghooni, Behnam, Virdee, Bal Singh, Denidni, Tayeb A.

“…The simulation and experimental results show that the main beam of the antenna in the E-plane is tilted by 17 degrees with respect to the end-fire direction at 7.3, 7.5, and 7.7 GHz. Results also show unlike conventional beam-tilting antennas, no gain drop is observed when the beam is tilted; in fact there is a gain enhancement of 2.73 dB compared to the original bow-tie antenna at 7.5 GHz. …”
