Abstract：

Antennas　are　essential　components　of　any　wireless　system　due　to　their　irreplaceable　functions　in　transmitting　and　receiving　electromagnetic　waves.　Antenna　radiation　is　based　on　the　free　electron　resonance,　leading　to　a　concrete　relation　between　its　physical　size　and　operating　frequency.　This　fundamental　principle　makes　it　unrealizable　to　design　well-radiated　antennas　with　extremely　small　dimensions,　e.g.,　milli-wavelength　scales.　Here,　to　overturn　this　commonsense　correlation,　an　extremely　miniaturization　methodology　of　antennas　is　developed　by　integrating　an　arbitrary-sized　antenna　with　an　ohmic-biased　transistor　(OBT)　circuit.　In　this　way,　we　thousandfold　miniaturize　the　antenna　to　an　overall　size　at　milli-wavelength　scales,　including　the　OBT　circuits.　Proven　by　the　experiments　in　the　demonstration　systems,　the　wireless　system　with　this　thousandfold　miniaturized　antenna　receives　electromagnetic　waves　well.　This　methodology　would　be　widely　utilized　in　space-limited　wireless　systems　that　cannot　provide　enough　space　for　antennas,　benefiting　various　exciting　areas,　such　as　information　technologies,　photoelectricity　physics,　biomedical　science,　and　so　on.　Copyright　©　2025　The　Author(s).
