A Multiband Biconical Log-periodic Antenna for Swarm Communications

In this paper, we present a specific multiband antenna design that addresses the problem of communication with unmanned aerial vehicles (UAVs). We consider a scenario where multiband single-antenna UAV communicates with the rest of the swarm members that are equipped with similar antennas. The key point in the design is that the communication does not require high or low elevation angles in most of the cases. The suggested design has a sufficient degree of freedom to select the desired features for the field pattern while keeping other features such as antenna impedance and gain relatively stable or at least in the acceptable operation region.
