1. A tunable antenna, comprising:
a substrate, and a microstrip feeder and a plurality of antennas arranged at intervals on a side of the substrate, wherein the microstrip feeder is configured to provide a coupling signal; and
a control switch, arranged between the microstrip feeder and the plurality of antennas, and/or between at least two adjacent antennas the plurality of antennas,
wherein the control switch is configured to control conduction between the microstrip feeder and at least one of the plurality of antennas, so as to output the coupling signal provided by the microstrip feeder into electromagnetic waves of different frequency bands,
the control switch comprises a microelectromechanical system (MEMS) switch, and the MEMS switch comprises at least a cantilever beam and a drive electrode arranged corresponding to the cantilever beam, wherein the drive electrode is configured to apply a driving voltage,
the cantilever beam comprises a fixed end and a movable end, and the movable end is configured to contact with or separate from the antenna under an action of the driving voltage, and
an insulating boss is arranged on a side of the substrate, the antenna covers the insulating boss, and an orthographic projection of the insulating boss on the substrate is an overlapping area of an orthographic projection of the movable end of the cantilever beam on the substrate and an orthographic projection of the antenna on the substrate.
