1. An electronic device, comprising:
a signal transmission structure having a waveguide and a plurality of first slots configured to radiate an electromagnetic wave, wherein each of the plurality of first slots is adjustable by a circuit to control a radiation direction of the electromagnetic wave,
wherein the circuit is configured to drive at least one of the plurality of first slots operating in an On or Off mode,
the circuit comprises at least one switch element across the at least one of the plurality of first slots, and
the switch element comprises at least one first diode configured to determine the On or Off mode of the at least one of the plurality of first slots by turning off or turning on the at least one first diode.
