A novel cavity‐stabilized, Gunn‐diode‐driven, self‐mixing slot‐line active antenna has been developed. The active antenna provides good radiation patterns with cross‐polarization levels 10.5 dB below copolarization at boresight. The self‐mixing performance shows that the circuit has a 1.6 dB isotropic conversion gain for IFs up to 250 MHz with good stability. The antenna is suitable for use as a transceiver for RF identification or as a collision‐warning radar. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 17: 27–29, 1998.
