Abstract : A self-mixing antenna-mixer millimeter wave receiver has the local oscillator and the mixer combined in one single unit, using a Gunn diode (or other device) placed at the center of a spiral antenna and proper voltage applied, so that the diode becomes an oscillator. At the same time the diode will function as a mixer for the input signals received by the spiral antenna. The IF frequency from the mixer can be amplified and detected for further processing. Only a dc power supply is required to feed the diode at the center of the antenna.
