Recently, the use of millimeter wave (mmW) frequencies has emerged as a\npromising solution for wirelessly connecting unmanned aerial vehicles (UAVs) to\nground users. However, employing UAVassisted directional mmW links is\nchallenging due to the random fluctuations of hovering UAVs. In this paper, the\nperformance of UAV-based mmW links is investigated when UAVs are equipped with\nsquare array antennas. The 3GPP antenna propagation patterns are used to model\nthe square array antenna. It is shown that the square array antenna is\nsensitive to both horizontal and vertical angular vibrations of UAVs. In order\nto explore the relationship between the vibrations of UAVs and their antenna\npattern, the UAV-based mmW channels are characterized by considering the large\nscale path loss, small scale fading along with antenna patterns as well as the\nrandom effect of UAVs' angular vibrations. To enable effective performance\nanalysis, tractable and closed-form statistical channel models are derived for\naerial-to-aerial (A2A), ground-to-aerial (G2A), and aerial-to-ground (A2G)\nchannels. The accuracy of analytical models is verified by employing Monte\nCarlo simulations. Analytical results are then used to study the effect of\nantenna pattern gain under different conditions for the UAVs' angular\nvibrations for establishing reliable UAV-assisted mmW links in terms of\nachieving minimum outage probability.\n
