In this paper, a two-dimensional cylindrical Lens antenna based on the\nparallel plate technique is designed. It supports beam-steering capability of\n58 degree at 28 GHz. The antenna is composed of low loss rectangular waveguide\nantennas, which are positioned around a homogeneous cylindrical Teflon lens in\nthe air region of two conducting parallel plates. The Beam scanning can be\nachieved by switching between the antenna elements. The main advantages of our\ndesign include its relative simplicity, ease of fabrication, and high-power\nhandling capability. Compared to previous works including a curvature\noptimization for the plate separation of the parallel plates, the proposed\nantenna has a constant distance between plates. At the 28 GHz, the maximum\nsimulated gain value is about 19 dB. Furthermore, the designed antenna only\ndeviates about 0.4 dB over the 58 degree scan range.\n
