Unmanned aerial vehicle communication

An unmanned aerial vehicle (UAV) comprising:

• a modem comprising an antenna port;
• antennas configured to generate a directional transmission pattern connected to the antenna port, the antennas including (a) an array of omni-directional antennas and (b) multiple directional antennas;
• beam control circuitry to provide control signals to the antennas to control a direction of the directional transmission pattern;
• and
• a memory including data indicating a parameter of a respective base stations of a communications network through which the UAV modem is configured to communicate.

An antenna device comprising:

• a driver structure;
• a first director situated a first distance away from the driver structure in a first direction and configured to guide signals at a first range of frequencies from the driver structure;
• a first reflector situated about the first distance away from the driver structure in a second, opposite direction, the first reflector to direct signals from the driver structure at the first range of frequencies towards the first director;
• a second director a second distance away from the driver structure in the first direction and configured to guide signals at a second range from of frequencies from the driver structure;
• and
• a second reflector situated about the first distance away from the driver structure in the second direction, the second reflector to direct signals from the driver structure at the second range of frequencies towards the first director.
