How do antennas work if DC cannot pass through air

The long range fall off of electromagnetic field strength cannot make electrons drift, just like how sound doesn’t move without a medium. However, AC, although it does not transmit power with a reasonable strength wirelessly, canincomplete

Also, the impedance of free space is 377 ohms. $Z_0=\frac{|E|}{|H|}=377\text{ohms}$
