“…Printed leaky wave antennas [1]- [2] are common for frequency scanning purpose. Although printed structures are suitable for integration, they suffer from low efficiency due to high metallic loss at high frequency owing to the finite conductivity of the metal.…”

A new dielectric grating antenna is proposed in this paper. The proposed all-silicon antenna consists of a rectangular dielectric waveguide with rectangular gratings on its both sides. This type of grating can be fabricated with low cost single print deep reactive-ion-etching process. The radiation mechanism in the proposed structure, is based on the power leakage of the order -1 space harmonic (Floquet's mode). The proposed optimized 94GHz antenna is well-matched over a more than 10% bandwidth with a frequency scanning ability up to 25 o (1dB variations in the gain).
