If your drone had a way to communicate with the external world that would be its achilles heel. Im sure this is being researched as we speak and this type of defense weapon will make an impact on FPV warfare drones, maybe they will be designed in a new way to combat this or they’ll learn to detect what to stay away from.
adjustable attenuators are well known already. Software inside the drone can dial up the attenuation on the antenna whenever it is under attack.
Also, by using ultra wideband for the comms, there will always be some frequencies that an attack isn't happening on - and sets of notch filters can let those through.
