N2 - In this paper, a new self-oscillating mixer (SOM) including a dielectric resonator (DR) antenna fed by a half-mode substrate integrated waveguide (HMSIW) has been proposed using hybrid integrated circuit technique on an FR4 epoxy substrate. The HMSIW resonator with high quality factor and the DR radiator with higher order HEM13δ mode excitation are responsible for the excellent phase noise performance of the oscillator and the high directivity of the antenna, respectively. The phase noise, estimated LO power, and conversion gain were obtained as −102.5 dBc/Hz at 1 MHz offset, 8.74 dBm at an oscillation frequency of 24.15 GHz, and 8.5 dB, respectively. The figure-of-merit for the oscillator was obtained −172.8 dBc/Hz.
