I think something cooler would be a fleet of micro-drones that seek out and destroy other drones. Since it doesn't need to have a transceiver itself, seeking out anything broadcasting from above it at ~2.4ghz would be a challenge, but not impossible.
They don't even need to have explosives. Just speed and a good collision path. If it tracks someone's cell phone that could be awkward, but not deadly.
I find ground-based systems more effective as a defensive measure, tho. No limit on weight, no added energy consumption just to be ready to react. I think germans showcased some autocannon like that. It's easier to spot and destroy, but also easier to maintain a drone-less perimeter.
On the other hand, flying antidrone fleet can be an offensive weapon. Everyone watches the front from the sky nowadays, so quickly pulling their eyes off before pushing forward can be a lifesaver.
That's Gepard, but there are also laser based weapons and loads and loads of EW (mostly jammers)
