Abstract: Dynamic shielding of cellular signals for an antenna of an unmanned aerial vehicle is disclosed. An example method may include receiving a navigation route for an unmanned aerial vehicle to execute during flight of the unmanned aerial vehicle and determining an orientation of a radio signal shield for an antenna of the unmanned aerial vehicle using ground level signal propagation information of radio signals for a network and the navigation route, wherein the radio signal shield prevents the radio signals from being received by the antenna from directions based on the orientation. The method may further include adjusting the radio signal shield using the orientation and communicating with a cellular base station of the network using the antenna.

Abstract: Examples are disclosed that relate to controlling an electronic device including a multi-mode antenna system. In a first operating mode, a radio signal is transmitted via a first antenna, a second antenna is actively de-tuned the while receiving a reflected radio signal thereby increasing isolation between the first and second antennas, an object is detected based at least on the reflected radio signal and the multi-mode antenna system is switched to operation in a second operating mode. In the second operating mode, a first remote radio signal transmitted by a remote antenna of a remote electronic device is received, via the first antenna, a second remote radio signal transmitted by the remote antenna is received via the second antenna, and a position of the remote electronic device is determined based at least on a phase difference between the first remote radio signal and the second remote radio signal.
