One of the challenges of designing UAVs is the limited amount of interior space for components. The communication, navigation, and radar systems all compete for this limited space. Phased array antenna systems, in turn, save space, weight, and power by steering the antenna electrically versus mechanically. Rotman lens devices (Fig. 1) are a particularly efficient means providing the correct amplitude and phase waveform inputs to a phased array antenna to allow this steering. However, the elongated, flat shape of a Rotman lens makes it cumbersome to fit the confines of a UAV.
