This paper proposes the holographic antenna using slotted hologram patterns for high efficiency at 24 GHz. The 4 slotted quasi-Yagi antennas are arrayed as a surface-wave launcher. The proposed antenna using the slotted patterns provides the higher gain at the broadside direction and more compact size than conventional holographic antennas with metal line patterns. The proposed antenna has the maximum gain of 15.8 dBi at broadside direction and the aperture efficiency is 30.65%, which is higher than 9.25% compared to the conventional antenna.
