  Millimeter wave (mmWave) communication represents one of the main innovations
of the next generation of wireless technologies, allowing users to reach
unprecedented data rates. To overcome the high path loss at mmWave frequencies,
these systems make use of directional antennas able to focus the transmit power
into narrow beams using BeamForming (BF) techniques, thus making the
communication directional. This new paradigm opens up a set of challenges for
the design of efficient wireless systems, in which antenna and BF components
play an important role also at the higher layer of the protocol stack. For this
reason, accurate modeling of these components in a full-stack simulation is of
primary importance to understand the overall system behavior. This paper
proposes a novel framework for the end-to-end simulation of 5G mmWave cellular
networks, including a ray-tracing based channel model and accurate models for
antenna arrays and BF schemes. We showcase this framework by evaluating the
performance of different antenna and BF configurations considering both
link-level and end-to-end metrics and present the obtained results.
