Optical wireless links can offer a very large bandwidth and can act as a complementary technology to radiofrequency links. Optical components nowadays are however rather bulky. Therefore, we have investigated the potential of silicon photonics to fabricated integrated components for wireless optical communication. This paper presents a two-dimensional phased array antenna consisting of grating couplers that couple light off-chip. Wavelength steering of $0.24°/nm is presented reducing the need of active phase modulators. The needed steering range is $1.5°. The 3dB angular coverage range of these antennas is about $0.007π sr with a directivity of more than 38dBi and antenna losses smaller than 3dB.
