Is paywalled for me, do they explain the range and how much power they are throwing? An altitude of 15m suggests this thing needs to be pretty close ..
I don't think this is the full article (with 3rd-party js disabled) but the web archive didn't get more out of it either.

China’s ‘land aircraft carrier’ charges flying drone with microwave beam
While the technology is still at an early stage, it may one day allow drones to fly indefinitely

A vehicle that can zap energy into a fleet of drones, allowing them to fly indefinitely, is getting closer to becoming a battlefield reality.
Scientists in China have demonstrated a wireless power transmission system that uses a ground-based microwave emitter to beam energy to an antenna array mounted on the aircraft’s underside. Importantly, they were able to do this while both the drone and charging system were in motion.
Some analysts have likened the concept to a “land-based aircraft carrier”, in which an armoured vehicle could function as a mobile command and energy node, launching and sustaining drones much just as naval carriers support aircraft.
They say such systems could extend the operational reach of ground forces, enabling persistent surveillance, airborne attacks and electronic warfare.
The findings were published on March 25 in the peer-reviewed Chinese journal Aeronautical Science & Technology by a team from Xidian University, which is known for its military technology research.
In tests, the car-mounted system kept fixed-wing drones in the air for up to 3.1 hours at an altitude of 15 metres (49 feet). The key challenge that the team overcame was maintaining alignment between the emitter and the drone during flight, wrote Song Liwei, the project’s leader.
To do so, the researchers integrated GPS positioning, a dynamic tracking system and onboard flight controls into the system.
I feel like practically this isn't very helpful. The car (or other much larger aircraft needs to pace the drones or vice versa and be in very close proximity, surely landing and hotswapping a battery pack would be faster and more efficient. Like if landing isn't an option is driving a car over garbage terrain while maintaining proximity to a low flying aircraft going to be possible? I guess you could use a blimp or large aircraft to pace the drones, but not sure a blimp and drone could match speeds without one breaking up or the other falling out of the sky.
