Query: Performance Analysis of Mobile Cellular-Connected Drones under Practical
  Antenna Configurations   Providing seamless connectivity to unmanned aerial vehicle user equipments
(UAV-UEs) is very challenging due to the encountered line-of-sight interference
and reduced gains of down-tilted base station (BS) antennas. For instance, as
the altitude of UAV-UEs increases, their cell association and handover
procedure become driven by the side-lobes of the BS antennas. In this paper,
the performance of cellular-connected UAV-UEs is studied under 3D practical
antenna configurations. Two scenarios are studied: scenarios with static,
hovering UAV- UEs and scenarios with mobile UAV-UEs. For both scenarios, the
UAV-UE coverage probability is characterized as a function of the system
parameters. The effects of the number of antenna elements on the UAV-UE
coverage probability and handover rate of mobile UAV-UEs are then investigated.
Results reveal that the UAV-UE coverage probability under a practical antenna
pattern is worse than that under a simple antenna model. Moreover,
vertically-mobile UAV-UEs are susceptible to altitude handover due to
consecutive crossings of the nulls and peaks of the antenna side-lobes.
