Millimeter wave (mmWave) carrier frequencies, a key feature of 5G cellular systems, are ideally suited to provide high data rates thanks to higher‐bandwidth channels. This chapter explains the potential of mmWave for unmanned aerial vehicles (UAVs). Then it summarizes important considerations for propagation at millimeter wave frequencies and reviews appropriate channel models for different scenarios. The chapter describes the fundamental challenges related to UAV multiple input–multiple output (MIMO) communication at mmWave frequencies, including the use of large arrays, high mobility, and less structured mobility. Links between UAVs are challenging to establish and maintain because both nodes are highly mobile, although the channel is usually line‐of‐sight and a single path is enough to accurately model the propagation environment. The chapter concludes by describing additional research opportunities that are pertinent for UAVs operating at mmWave frequencies.
