Due to limited and expensive spectrum availability at lower microwave frequencies (up to ≈10 GHz), the 60 GHz mm-wave spectrum, can be seen as a first step towards the inevitable transition to mm-wave technology. While this transition may simplify system architectures, the current microwave technologies are not directly scalable and novel solutions are needed. This thesis concerns with controlling propagation characteristics of mm-waves using Electromagnetic metasurfaces, which are 2D counterparts of metamaterials. Metasurfaces could be envisioned to be used as standalone devices in various RF environments to control wave propagation. In this work, an all-dielectric implementation of mm-wave metasurfaces is investigated. Compared to the existing PCB based designs, the all-dielectric metasurfaces are simple to design, while requiring a non-conventional micro machining process. Various metasurfaces at 30 GHz are designed and demonstrated in the thesis. To push the limits of the design, a 60 GHz metasurface is fabricated to achieve beam-broadening.
